Old Dakota at entrance to Jacksons Airport.
For the 2010 field trip to PNG, my 9th visit to the country, I was based at the Gateway Hotel, as were Roger Lowe and Steve Slater during their two week each visits. The Gateway was extremely handy, close to the airport (the old Dakota was right outside the gate), handy for Port Moresby General Hospital and the AVRU Serpentarium and within easy access of the Hiritano and Magi Highways. Heroping in the grounds produced one species, the Slender forest skink (Sphenomorphus cf. fragilis), found under pot-plants. I would also expect the Brahminy blindsnake (Ramphotyphlops braminus) but did not find it there yet.

The commonest snakes seem around Port Moresby city were DOR Carpet pythons (Morelia spilota harrisoni), although whether they were killed by traffic or killed elsewhere and thrown onto the road, would be impossible to determine without closer examination, which would risk joining the python by being run over. We counted at least a dozen DOR carpet pythons around the capital, and more beyond on the Hiritano Highway. The only DOR snake we stopped to collect was a recently killed Black whipsnake (Demansia vestigiata), on the inside ofthe curve at Goanna Corner. Goannas Corner is a location on a wide bend where, driving out of town, Roger, Owen, Jasper and I pursued a large Papuan savanna or Argus monitor lizard (Varanus panoptes hornii). We failed to capture the lizard but drew a large crowd, several of whom offered to catch and sell the lizard to us. We declined and left.
The whipsnake was fresh enough to warrent removal of the venom glands for Owen. Whilst I was excising the glands I noticed a large lungworm (Nematoda: Strongylida) which exited the nares. I have found these parasites in whipsnakes before, ie. a specimen given to me alive in the Mekeo region of Central Province in the eaarly 1990s went into a fit and died. Immediately afterwards two large lungworms were captured as they exited the glottis. These parasites may be part of the reason for the apparent decline of whipsnakes in Central Province.

All specimens were documented, photographed and identified with DNA samples being taken from voucher specimens (blood, tissue, scale-clips and/or liver). Voucher specimens will be deposited in the Bishop Museum, Honolulu, which is the center for Papuan Herpetofaunal Research.
We spent a great deal of time at the AVRU Serpentarium feeding death adders, milking the eight taipan, examining specimens, doing photography etc.

One of the sadest duties was looking after the oldest taipan in residence, a 2.7m specimen called Fat Albert which had a pre-clocal tumour. This snake had been in the programme since 2004 and when it passed away it was mourned in PNG, Australia and Europe.
The healthy taipan were to be milked every three weeks which meant I got two sessions in during my visit. Roger also milked two taipan during the first session and Steve and Owen milked on each during the second session. I dealt with the rest including the newly captured, settled, fed and sloughed Dasiama specimen. All venom was pooled for the monovalent taipan antivenom production programme.

One of the taipan in the Serpentarium was actually captured outside the unit, there are taipans living wild on the hospital campus. Although nothing quite like that turned up during our stay we did catch and photograph some interesting spiders.
Whilst in Port Moresby I was asked to give a lecture at the Port Moresby Internaional School (POMIS). I last spoke there following my first ever visit to PNG in 1986 so it was a pleasure to return and speak there again almost a quarter of a century later. I spoke about how field science is fun and also gave the students an introduction to the snakes of Papua New Guinea. Steve and Owen assisted with a demonstation of the correct first aid procedures for snakebite in PNG and then introduced the students, staff and visitors to a couple of Southern white-lipped pythons (Leiopython hoserae).
