No. 1. — Some Reptiles and batrachians from Australasia. 
By SAMUEL GARMAN. 
Many of these specimens were taken, at various localities, by mem- 
bers of Mr. Alexander Agassiz’s Expeditions to the Great Barrier Reef 
of Australia and to the Fiji and Samoan Islands, and a large number 
were donated by Mr. E. A. C. Olive, who had made Cooktown, Queens- 
land, the point of departure for his collecting excursions. Among 
them there are certain types that are particularly interesting, since they 
are closely allied to others, already described, from the southern and the 
western parts of Australia, and yet are sufficiently distinct to demand 
descriptions and names, on account of importance in considerations of 
distribution and derivation. While some of them appear to be new, all 
of them have close affinities with species more or less widely distributed 
in the region. In the collection there are thirty-four species, and 
these pertain to twenty-two genera of fourteen families. 
Gymnodactylus pelagicus Bout. 
Heteronota pelagica Gir. 
Individuals taken on the Barrier Reefs, by the members of the expedition, 
and at Cooktown, by Mr. Olive, agree well with the original description drawn 
from those taken on the Fiji and Navigator Islands. The rows of tubercles 
vary in number from sixteen to eighteen ; the small scales of the dorsum have 
three or more keels ; and on some the labials number eight upper and six 
lower. 
Gymnodactylus Olivii, sp. nov. 
Plate 1, Fig. 1-14. 
Head large, depressed, widest across the space between the ears and the eyes, 
three-fourths as wide as long, tapering from the postocular region to the snout. 
Snout nearly one-third longer than the space between the orbits and the ear, 
blunt. Forehead slightly concave. Ear opening small, subtriangular. Body 
moderately depressed ; limbs moderate ; digits depressed at the base, com- 
pressed in the distal portion, with broad transverse plates under the basal joint ;
