are extremely thin. In the male antennulae the two distal peduncular joints 
are somewhat shorter and much thicker than in the female; the upper flagellum 
is slightly longer than the peduncle and conspicuously shorter than the lower; 
both flagella distinctly thicker than in the female, but any expansion or flatten- 
ing is not distinct, and the joints, probably eight, are difficult to count.— The 
antennal squama is very long and narrow, 13-14 times as long as broad a little 
behind the base of the marginal tooth; in the female it scarcely reaches to the mid- — 
dle of third joint of the antennular peduncle, in the male scarcely to the end of the 
same joint.— The false chelae of second pair of legs in the main as in S. affine. 
Sixth abdominal segment (fig. 3b) a little less than twice as long as deep, 
with the lower margin curved moderately strongly upwards towards the end.— — 
The rami of the uropods nearly equal in length, reaching scarcely the end of 
telson. 
Length of the males 5-5.5 mm., of the females 5-5.8 mm. 
Remarks.— It may be seen from the description that this species is very 
closely allied to S. affine H. J. H. and S. longicorne G. O. 8S. But it is easily 
distinguished from both by the eyes which, seen from the side, are slender, 
extend very much beyond the upper end of the stalk and show only three erystal 
cones in the transverse row. 
Distribution.— The type of Sars, preserved in the British Museum, is from 
the Pacific, North of New Guinea. His specimen from ‘“‘off Luzon, China Sea,” 
is damaged, but seems to belong to this species. Whether the specimen from 
his third locality, ‘‘Samboangan to Ho-Ho, Philippines”’ in reality belonged to 
this species cannot be decided, as it seems to be lost. I discard all other state- 
ments in the literature before 1910 as uncertain, because several and perhaps 
many among them belong to other species; it may only be stated here that the — 
Monaco material from the temperate North Atlantic comprises a number of 
specimens.
