The specimen of this little species showed no distinctive sexual characters. 
In the first antennz the flagellum is six-jointed, in the second thirteen- 
jointed. The apex of the telsonic segment is bordered with eight spines, not, 
indeed, on the outer case, which was almost denuded of its fringe, but on that 
prepared for the moult, which came away clear in dissection. 
The length of the specimen was 4°5 mm., with a breadth of 1:25 mm.

The four species of this genus already described are closely related one to 
the other, and the species now to be added is evidently a near ally of the 
rest. It belongs to the group in which the hinder part of the body is 
setigerous, and agrees with the form which I have named L. gardineri in 
having a frontal process to the head of the male. The process, however, 
is not horn-like, but distally expanded, so as to present a very distinct — 
appearance, 
LANOCIRA LATIFRONS, sp. n. (Plate 21.) 
In the male the front of the head is produced into a broad, slightly 
upturned, somewhat axe-like process, of which the widened distal portion 
while in sctu appears to be truncate in dorsal view, but is seen to have a 
eurved outline when the head is detached. In the female there is only 
a broad shallow convex projection, in no way axe-like. Of the person 
segments, the first is the largest, the last three are successively smaller than 
those which precede them. ‘The first pleon segment is almost completely 
concealed, and the fifth has its outer angles much overlapped by those of the 
preceding segment. The telsonic segment is broader at the base than the 
length, that part of it which no doubt represents the telson being triangular 
with a rather narrowly rounded apex. The surface is pretty closely set with
