VALLENTINIA. 173 



the basal joint armed interiorly with only two spine-like 

 setse, while the small secondary joint is armed similarly to 

 the same joint in the female. 



The genus Vallentinia differs from Dactylopodella, which 

 it somewhat closely resembles, chiefly in the structure of the 

 inner rami of the second pair of thoracic feet in both sexes 

 and in one or two other minor points.

 Hist. ser. 7, vol. xv. p. ^94. 



Description of the female. Body moderately robust and 

 somewhat similar in form to Dactylopusia rostrata (T. Scott), 

 but scarcely more than half the size ; length of the specimen 

 represented 'by the drawing (PI. XIX. fig. "2} is 'G2 mm. 



(4*0 f an inch). 



Antennules short, moderately stout, and composed of six 

 subequal joints (PL XXI. fig. 4). 



.An ten use somewhat like those of Dactylopusia rostrata 

 (T. Scott), the secondary branches being also as in that 

 species apparently only two-jointed. The other cephalic appen- 

 dages appear also to be similar to those of the same species. 



The first pair of thoracic feet (PI. XVI. fig. 8) are short 

 and stout. The outer ramus is three-jointed and shorter 

 than the first joint of the inner ; the first and second joints 

 are of moderate size, and each has the outer margin fringed 

 with short set*, while a setiferous spine springs from its 

 outer distal angle ; the second joint bears also a plumose 

 seta on its inner margin ; the end joint is very small and 

 furnished with several spiniform apical setse. The inner 

 ramus appears to be only two-jointed, the first joint being 

 stout and longer than the entire outer ramus; this joint 

 bears a moderately long plumose seta on its inner margin ; 

 the end joint, which is short, is armed with a stout and 

 slightly curved claw-like terminal spine and one or two 

 setse as in the drawing. 



The next three pairs resemble those of D. rostrata (see 

 fig. 10, PI. XVI., which represents the fourth pair). 



The fifth pair in the female (PI. XVIII. fig. 7) are broadly 

 lamelliform ; the basal joint, which is only moderately pro- 

 duced interiorly, bears five spiniform set* of varying lengths 

 on its broadly rounded distal margin. The secondary joint, 

 which is subquadrangular in outline, is also provided with
