REPORT ON A ZOOLOGICAL COLLECTION FROM 
BRITISH NEW GUINEA. 
The following Report deals with certain Reptiles, Batrachians, 
Fishes, and Insects forwarded for identification to the Australian 
Museum by Sir William Macgregor, K.C.M.G., Administrator 
of British New Guinea, who had caused them to be collected in 
the St. Joseph’s River District ; this river flows into the Papuan 
Gulf opposite to Yule Island, about eighty miles to the north-west 
of Port Moresby, and is said to take its rise in the range which 
culminates to the eastward in Mount Yule. 
Part I. 
REPTILES, BATRACHIANS, AND FISHES. 
By J. Douglas Ogilby. 
This portion of the collection contained in all nineteen species, 
belonging to twelve genera ; these are divided as follows : — one 
Emydosaurian (Crocodilus) : six Lacertilians (Lialis 1, Gonyo - 
cephalus 2, Lygosomct 3): three Ophidians (Morelia 1, Bracliysoma 
1, Acanthopliis 1 ) : one Batrachian (Hyla 4) : and four genera of 
Fishes (Eleotris 2, Salarias 1, Plotosus 1 : Syngnathus 1 ). 
Unfortunately all the Fishes and two of the Batrachians were 
too young to be recognizable. 
Full particulars are given below : — 
REPTILIA. 
EMYDOSAURIA. 
This Order is represented by a single young example of 
Crocodilus porosus , Schn. 
LACERTILIA. 
The Lacertilian Reptiles are represented by six species, and 
comprise a Lialis , two species of G onyo cephalus, and three of 
Lygosoma. Of the correct identification of neither species of 
Go'iiyocephalus am I absolutely certain, but I consider it preferable 
to name them as below, those being the species to which indubitably 
they are most nearly allied, than to risk a possible multiplication 
of synonyms by describing them as new. In this uncertainty, 
however, I have thought it advisable to describe both species in 
detail, so as to afford an opportunity to herpetologists of forming 
their own opinion as to the identity, or otherwise, of the species 
under consideration. The Skinks are also interesting, inasmuch 
as it has been found necessary to describe one new species, while,
