Four specimens of the male sex, in length about 2°5 mm., agree closely 
with Dana’s figures. They are well distinguished trom ZL. mirabilis, of 
Professor Herdman’s expedition, not only by much inferior size, but also by 
he second joint of the upper antennze, which is here barely twice, instead of 
eight times, as long as the third. The flagellum is eight-jomted. Along 
with these male specimens were several others, ranging from 2 mm. to 
3°75 mm. in length, without the characteristic gnathopods of the adult male, 
and some of them declaring their sex by having eggs in the marsupium.

A single specimen of the adult male with the characteristic first gnatho- 
pods occurred in the collection. The gnathopods in question are substantially 
constructed as well as elongate, with a wide gap left between the finger and 
the strongly bidentate thumb, when they meet. In this specimen the uro- 
pods have the longer ramus five-jointed, but the shorter one-jointed, not 
two-jointed as in the typical specimens. 
Locality. Suez docks, among broken shells, 7/12/4. At a locality labelled 
04/5, 11 Misc. 30, several specimens occurred which are probably the females 
or young males of this species. Some of these had the four pairs of 
marsupial plates well developed. A few also occurred along with Tanais 
phileterus above mentioned, and a single larval specimen of Gnathia. 
Tribe /LABELLIFERA.
