OF NEW ZEALAND. 7a 
about as long as abdomen. A spine at lower apex of wrist. Length 
nearly 2 in. (D.). . 
New Zealand, Bay of Islands (Dana); South side of Davis Straits 
(Coll. Brit. Mus.). 
I have given above Dana’s description of the species he refers to 
G. hirtifrons, a specimen in the British Museum Collection agrees well 
with it. The front is strongly three-lobed, the lobes triangular, acute, 
the middle one the longest. 
In the typical specimen of G. hirtifrons in the Collection of the 
British Museum, the front is triangular, hairy and scabrous, hardly, if 
at all, three-lobed; the hand slender, hairy on its outer surface, and 
not denticulated below, the immobile finger quite rudimentary. Wrist 
with a spine at its upper apex, and one on the inner surface, but none 
at the lower apex. The specimen was obtained during the Antarctic 
Expedition, but is without any definite indication of habitat.
