A New Victorian Blind Amphipod. 157 



angle, there is a row of about three long setae, and another row 

 of about four similar setse, near the front margin, about midway 

 between the proximal and distal ends. The dactylos is long, 

 slightly curved, margins entire, and the extremity acute. 



Pereiopoda (Fig. 10). — The first pereipod is slender and about 

 one-fourth longer than the second gnathopod. The basos is 

 narrowly oblong, with two or these very long setse on the hinder 

 margin. The ischios is subrectangular, with a tuft of setae at 

 the postero-distal angle. The meros is oblong and slightly 

 produced at the antero-distal angle, and possessing a few setae 

 on the anterior and posterior margins, and also tufts at the 

 antero- and postero-distal angles. The carpus is somewhat 

 shorter than the meros, with margins nearly straight, and- 

 having a tuft of setae on the antero-distal angle, and a few 

 scattered setae on the hinder margin. The propodos is slightly 

 longer than the carpus, but narrower, ;ind the margins straight ,- 

 on the antero-distal angle there is a tuft of long seta?, and the 

 hinder margin is clothed with five short spinules. The dactylos 

 is very slightly curved, acute, and with a fine tooth distally. 



The second pereiopod is similar in all respects to the first. 



The third pereiopod is subequal to the first and second, but it 

 is reversed in its manner of articulation with the body, and is 

 rather stouter. 



The fourth pereiopod (Fig. 11, inside view), is longer and- 

 stouter than the third. The propodos has six short spines, 

 arranged in transverse pairs, at equal distances along the^ 

 anterior margin. 



The fifth pereiopod is much longer than the fourth, due to the 

 extra length of the carpus and propodos ; the other joints are 

 of similar length to the fourth pereiopod, and also of similar 

 form except the dactylos, which is in the fifth almost straight, 

 but, as in the other pereiopods, it has a fine lateral tooth- 

 distally. 



Pleopoda (Fig. 12). — The pleopoda are of the usual shape, the 

 anterior pair being somewhat the longer. Distally, on the inner 

 surface of the peduncle, there are two " coupling spines " (12rt), 

 and on the first joint of the inner ramus there are four "cleft- 

 spines" (12/'), in two longitudinally disposed pairs.
