The carapace, which is 10 mm. in length, corresponds closely 

 with that of Alcock's types; but it is perhaps not quite so strongly 

 narrowed anteriorly. 



The posterior parts of the carapace and the 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 III. Zool. Invest., Crust., 

 pi. Ixxii, fig. I, la). In E. hirsuta, however, the external orbital 

 spines are longer than in E. 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 E. andamanica than in E. hirsuta 

 and its internal margin is markedlj^ 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, pi. xiii, figs. 7, 8) 

 describes under the name of E. 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 dactyli of the 

 second and third peraeopods are longer than their propodites.

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
