224 Mr. E. J. Miers y« new Species of Crustacea. 



if at all, 3-lobed ; tlie hand slender, hairy on its outer surface, 

 and not denticulated below ; the immobile finger quite rudi- 

 mentary ; carpus with a spine at its upper apex and one on 

 the inner surface, but none at its lower apex. The specimen 

 was obtained during the Antarctic Expedition, but is without 

 any definite indication of habitat. 



Virhius bifidirostris, n. sp. Type, B.M, 



Carapace smooth, with two minute spines on each side below 

 the eyes. Rostrum slender, longer than the carapace, and 

 nearly as long as the scale of the external antennae, with two 

 teeth on the upper margin placed at some distance from one 

 another, and another, minute one near the apex, which thus 

 appears bifid ; lower margin with seven teeth. Scale of the 

 external antennee without a spine at base, but with a small 

 spine at the distal extremity of the outer margin. External 

 maxillipeds about reaching to the end of the peduncle of the 

 outer antenna? ; terminal joint dilated, minutely spinulous. 

 First pair of legs very short when directed forward, not reach- 

 ing to the end of the external maxillipeds. Second pair of 

 legs with the joints of the carpus short, the second the shortest. 

 Terminal segment of abdomen and caudal appendages slender. 



Length 1^ inch.

Alpheus novce-zealandicey n. sp. Type, B.M. 



Kostrum triangular, acute, rising at a considerable distance 

 behind the bases of the eyes, separated from the orbits by a 

 deep and wide groove, and projecting beyond the frontal margin 

 of the carapace nearly to the extremity of the first joint of the 

 inner antennfe. Interocular part of the frontal margin of the 

 carapace straight, without spinules, considerably more promi- 

 nent than the part exterior to the eyes. External antennte with 

 a very short spine at base, and another at the end of the last 

 joint of the peduncle ; the basal scale about equalling the 

 length of the peduncle. Anterior legs Avith the larger hand 

 elongate, twisted somewhat outwardly, with an obscure 

 oblique ridge above and below, without grooves or notches 

 except a short transverse groove behind the base of the mobile 

 finger, which is short, rounded above, and compressed. Wrist 

 of the second pair of legs with the first and second joints long, 

 nearly equal, together exceeding in length the last three joints, 

 Legs clothed Avith scattered hairs. 



Length about 2 inches.
