abdominal appendage, having indeed no rami, and, as far as I can make 

 out, Sars' species agrees in these particulars also. 



It appears to me therefore preferable that Sars' species should stand 

 as Concholestes pallidus (Sars). 



While, however, certainly congeneric, the two species are without 

 doubt specifically distinct, mine differing from G. pallidus in the even 

 more marked disproportion between the second and third thoracic 

 appendages, and in the third having a much better developed subchela, 

 which is formidably armed with two strong teeth, as also in having the 

 excessive length of the eighth less marked. 



Melita cotesi, n. sp., PL II, Fig. 1. 



This species is allied to M. leonis and M. formosa described by 

 Murdoch, P. U. S. Nat. Mus., VII, pp. 521. 



It illustrates the danger of naming a species from what may, at 

 first sight, appear a very prominent peculiarity. In a previous com- 

 m.unication, I described a Melita which I named megacheles on account 

 of the large size of the subchela of the second gnathopod, which 

 appeared larger proportionally than that of any species which I could 

 find described. Our present find, however, out-herods Herod in this 

 particular, and fearing to use any superlative appellation, lest another 

 even more formidably armed should turn up, I name it after Mr. Cotes 

 of the Indian Museum, but for whose kindness in undertaking the 

 wearisome work of searching through references while I was at sea, 

 this series of papers on Indian Amphipoda would have been greatly 

 delayed in appearance. 



About 7 mm. long ; semitransparent, with minute reddish dots 

 scattered over the whole surface, and an especially large patch on the 

 propodite and basipodite of the second gnathopod. 



Head small, no larger than an average thoracic segment ; eye small, 

 round, placed in the angle between antennules and antennse. 



Thorax forms more than half the length of the body ; coxal plates 

 rather narrow, especially the hinder ones. 



Abdomen relatively small, the hinder edge of each segment save 

 the last shewing more or less distinctly three dentations on either side 

 of the middle line. 



Antenmdes nearly as long as the head and thorax, the peduncle, 

 the second joint of which is considerably the longest, forming rather 

 the shorter half ; appendix three-jointed. 



Antennoe rather shorter, the peduncle, whose first three joints 

 are very short, having the last two joints so long that the entire peduncle 

 forms at least two-thirds of the length of the organ.
