830 MAJOR ALCOCK. 



Diogenes, Dana. 



Three small species are represented in the collection. One of them is nearly related 

 to D. pallescens Whitelegge, from Funafuti, and is here described as a new species. Another 

 may perhaps be the young of D. pugilator Roux, a Mediterranean and Atlantic species which 

 is also found in the Red Sea and, according to Nobili, at Singapore. The third form seems 

 to be new, but it cannot be satisfactorily characterized from a single minute and damaged 

 specimen. 



8. Diogenes gardineri, n. sp. Plate LXVIII. fig. 1. 



The rostrum is a simple spinule, and both the chelipeds are pilose. 



Carapace elongate, nearly smooth, its antero-lateral borders finely serrulate. " Rostrum" 

 a slender spinule slightly longer than the ophthalmic scales. 



Eyestalks remarkably long, considerably longer than the anterior border of the carapace, 

 almost as long as the peduncle of the antennule and very much longer than that of the 

 antenna. Ophthalmic scales spinulose at the antero-internal angle. 



Peduncle of the antenna remarkably short, barely reaching to the base of the terminal 

 joint of that of the antennule. Antennal acicle a serrated spinule not surpassing the 

 penultimate joint of the peduncle. 



Chelipeds pilose. Left cheliped much the larger : when denuded its outer surface is 

 smooth except for a longitudinal series of three or four spines on the outer surface of the 

 carpus: the upper border of the merus is serrulate, and the lower outer border of the merus 

 and the inner and anterior borders of the wrist and the upper border of the palm are 

 spinulose : the outer surface of the palm is traversed by a longitudinal bulge, or low carina, 

 the summit of which is finely granulous. 



The 2nd and 3rd legs reach, or slightly surpass, the end of the left cheliped: they 

 are setose and, except for a spinule at the far end of the anterior border of the carpus, 

 smooth : the dactyli are longer than the propodites. 



Length of carapace about 4 mm. 



In the shell of a small species of Cerithiuni. 



Mahlos, Maldives, 23 fathoms; Minikoi. 



In the remarkable length of the eyestalk and the abbreviated antennal peduncle, this 

 species resembles D. pallescens Whitelegge, from Funafuti.
