proximal extension directed towards the base of the leg. The outer spine is in- 
serted at approximately the middle of the margin and the segment is rounded 
terminally, bearing a short spine. 
The male of salinus, first deseribed by Thompson and Neott (loc. cit) is of 
the same size as the female. In the species found here the male is distinetly 
smaller, Both sexes are further distingwished from salinus by the knob-like pro- 
jections on the cephalic segment,

Bix species have already been described as belonging to this genus, though 
males are known for only four. The female of a seventh is deseribed and keys tor 
the identification of the species are given below. It is not practicable to include 
Esterly’s (1911) species magnus in the key as the description is very brief and the 
figures very few; unfortunately also, {he male is unknown. 
Despite the difference in size there is a strong probability that magnus (1+1 
mm.) and latens (0-63 mm.) are identical, The fifth legs of the female are figured 
in both eases and show a strong resemblance, differing chiefly in the absence in 
magnus of the spinules surrounding the bases of two of the terminal spines of the 
exopod shown for latens, 
This leg in these species is quite different from those of other species, being 
characterized by the partial or apparent fusion between the first and second seg- 
ments of the endopod, both of which are unarmed, and the second segment being 
widened and extended into spurs on both sides distally so that the small terminal 
segment appears to be sunk into a recess. The end serment is produced into a 
spur at the outer distal corner and bears a small adjacent terminal seta, the inner 
corner being produced into a very small point. From the two descriptions and 
figures there is no reason for separating them as species and their oeeurrence 
lends further support since it has been shown that the Bermudan fauna is closely 
related to that of the Suez Canal zone (Willey, 1930, pp. 82,113), Tn the event: 
of this synonymy being established Gurney’s name will, of course, have to give 
way to Esterly’s.
