is steel blue on the back, passing into silvery white on the belly, and with 
a dark spot over the pectoral fins. The whole body is covered with minute 
pores. All the spines and rays of the dorsal fin are very feeble and difficult 
to count. The pectorals are shorter than the head, and twice the length of 
the ventrals. I can find no teeth on the vomer.

Length two and a quarter times the height, or three times the length of 
the head. Snout, about half the diameter of the eye, which goes two and 
two-thirds into the head. Upper maxillary, extending to posterior of orbit, 
dilated at the end. All the teeth on the jaws, palate, and vomer, very 
small. Interorbital space equal to the diameter of the eye, convex; scales 
ending before the middle of the eye. Nostrils and ridges on the top of the 
head, as in T. elongatus. Snout, with two spines, directed forward, one 
from each ridge. Infraorbita] slightly crenated along its inferior margin. 
Preoperculum divided by a deep channel, which is crossed at the angle by 
a strong rough projecting spine, which extends to the gill opening. Oper- 
culum, with radiating rough ridges and a single spine. Cheeks scaly. 
Scapular, with a spine equal to that on the operculum. Spines of the 
dorsal, short and smooth ; the third soft ray the longest, as long as the 
pectorals, which are rounded, and one-fifth of the length of the body. 
Caudal, forked, composed of 22 soft rays, with seven spines above and 
of the vent, slightly behind the pectorals ; they extend back to the end of 
the pectorals. Ventral keel, with eleven scales, each armed with a strong

much pleasure in naming it, 
LEPTOSCOPUS (?) AN GUSTICEPS. Hutton. 
This fish belongs to Dr. Giinther’s genus Crapatalus (Ann. Nat. Hist.” 
8rd series 7, p. 87), and is perhaps identical with C. nove-zealandia, the 
description of which I had not seen when describing the species.
