I912.] S. Kemp &R.B.S. SEWELL: Notes on Decapoda, III. 29 
The carapace, which is 10 mm. in length, corresponds closely 
with that of Alcock’s types; but it is perhaps not quite so strongly 
natrowed anteriorly. 
The posterior parts of the carapace andthe whole frontal 
border are beset with long setae and in the possession of such 
an investment on the former region the specimen approaches 
E. hirsuta, McArdle (1900, p. 474, and Ill. Zool. Invest., Crust., 
pl. Ixxii, fig. 1, 1a). In EF. hivsuta, however, the external orbital 
spines are longer than in EF. andamanica and have a different 
form, though they do not always reach beyond the tips of the 
frontal teeth as stated in McArdle’s description. The external 
orbital angle is much broader in EF. andamanica than in E. hirsuta 
and its internal margin is markedly sinuous in the former, straight 
or slightly concave in the latter. 
Except for the hairs on the cardiac and branchial regions we 
are unable to differentiate our specimens from the types of E. anda- 
manica and the possibility that such a character was originally 
present in the latter specimens, but was lost before they were 
examined, cannot be overlooked. 
The species which Doflein (1904, p. 27, pl. xiii, figs. 7, 8) 
describes under the name of FE. andamanica seems to differ in 
several material respects from the type specimens of that species. 
In the original examples the external orbital angle is decidedly 
broader than is shown in Doflein’s figures and the dactvli of the 
second and third peraeopods are longer than their propodites.

A single specimen, with carapace I9 mm. in length, was 
obtained at St. 391.

Eight specimens, ranging in length of carapace from 10°5 
to 23 mm., were obtained at St. 391. Doflein (1904, p. 41) regards 
this form as merely a sub-species of De Haan’s M. armata.

Nine males 13—23 mm. in length, and one huge ovigerous 
female, measuring 35 mm., were obtained at St. 391. The latter
