approach the apex, where they become curved. Second pair of gnathopoda 
having the propodos (in the male) much larger than that of the first pair. 
Two anterior pairs of pereiopoda short, having the basa very broad. Pos- 
terior pair of pleopoda having two rami, one of which is armed with one or 
more hooked spines. Telson squamiform." 
Podocerus frequens, sp. nov. Plate III., fig. 2. 
Eye moderately large round. Superior antenna as long as the inferior; 
first joint of peduncle stout, next two joints longer, equal in length, slender, 
flagellum considerably longer than the last joint of peduncle, secondary 
appendage of two or three joints; the whole of the inferior margin of 
antenna thickly fringed with long sete. Inferior antenne slender, last 
two joints of flagellum equal and longer than the preceding one, flazellum 
considerably longer than the last joint of the peduncle, inferior border of 
antenna fringed with long sete ; spines on flagellum even at the end are 
not much curved and not very strong. First pair of gnathopoda long but 
not very stout, carpus longer than propodos, hairy; propodos ovate hairy, 
dactylos with proximal half of inner edge serrate, distal half smooth. 
Second gnathopod with carpus short, triangular, propodos large, produced 
inferiorly into a strong tooth against-which the dactylos impinges, dactylos 
strong proximal half of inner edge serrated. First two pairs of pereiopoda 
. subequal, stout. Last three pairs stout, third smaller than the fourth and 
fifth. Last three pairs of pleopoda short all reachirg to the same point ; 
first pair the longest, rather slender, peduncle longer than the rami and 
produced between them into a sharp slightly curved spine which is about 
two-thirds as long as the rami; rami with short teeth on upper margins 
curving upwards; second pair with stout peduncle, rami more slender than 
peduncle, curved teeth on upper margins of peduncle and rami; last pair 
with stout peduncle narrowing at apex, rami small slender, nearly naked. 
Telson with two curved spines, and anterior to these one or two simple 
sete. 
Female.—Differs from above in having the propodos of second gnatho- 
poda less stout and wanting the strong process, but with two stout setze 
towards the end of the palm. 
Length about 1, of an inch. 
Hab. Lyttelton Harbour. 
This species appears closely to resemble P. validus, Dana, from Rio 
Janeiro, but that species has the inferior antenne “ very stout.” 
The process on the propodos of second gnathopoda of male varies in 
size in different specimens, and is often longer and more distinct than 
shown in fig. 2b.
