There can I think be little doubt that Ammothea magnirostris o£ Dohrn is 

 the Achelia hispida o£ Hodge. The most marked characteristic of the species 

 consists in the large fleshy tubercles, one o£ which is situated on each lobe of 

 the body, but these are not easily seen in unmounted and dirty specimens, 

 and were overlooked by Hodge. The substitution o£ hairs for spines on the 

 ilegs distinguishes the present from the preceding species and from A. Langi. 



The front margin of the cephalic segment is abruptly truncate, but the 

 corners are produced forwards into lobes (see Dohrn, pi. vi. figs. 1 & 3) ; 

 the ocular tubercle is less elevated than in its allies ; the rostrum is wide 

 centrall}^ as well as at its termination, and somewhat contracted at the base. 

 The palpi are very long, and when extended forwards surpass the length of 

 the rostrum by three and a half or four joints ; the five terminal joints are 

 subequal in length to each other. In immature specimens the chelifori 

 are remarkably long for the genus, and the chela itself is widely gapino-, 

 and the inner margin of the finger quite simple. What appears to be a 

 peculiarity in the species is that the rostrum is often bent downwards, and 

 the palpi turned completely backwards underneath the body, so as to be quite 

 invisible from the dorsal view.

Apparently this is closely allied to A. hispida, if it be not the same.
