AMPIIIPOD GENUS LEPTOCHEIRUS. 589 



slender, feathered set;e, or setiform spines, in addition to the other 

 spines. These are found on the under margin, 3 in uropod 1, 

 short, inset at intervals, and 2 ckisters of long ones in uropod 2, 

 near the apex. In uropod 3 (fig. 20) the outer ramus is fur- 

 nished with an apical clu.sterof 5 spines and 3 or 4 long feathered 

 setse similar to those of the 2nd uropod, and 1 cluster of small 

 spines midway, in IS'orman's specimen (2 clusters figured by Delia 

 Valle, probably from an older specimen) ; the inner ramus is tippad 

 with 1 stout spine and 1 seta, with 1 spine midway, in Norman's 

 specimen (2 in Delia Valle's). 



Telson. — The apical margin of the telson is represented iu Delia 

 Valle's figure as truncate, but, as in guttatus Grube, this appear- 

 ance is due to the angle at which it is carried. The margin is 

 really convex, but as in the natural position it is a little bent in 

 under, the convexity is not apparent from the dorsal view. 



Colour given by Delia Vallo a,s greyish yellow without markings ; 

 by Dr. Pesta as " gelbbniun, Auge schwarz" ; but, he adds, '' diese 

 Fiirbung diirfte nicht natiirlich sein." 



Distribution : — 



Bay of Biscay : Norman (38) p. 309, as L. hispinosus, 



depth 35-60 fathoms. 

 Naples : Delia Valle (21) p. 432, as L. guttatus ; bottom deposit, 



corallines. 

 Adriatic a.t Lesina : Heller (25) p. 35, as Protomedeia 



hirsutimana. 

 Gulf of Bone and Coast of Tunis: Chevreux (18) p. 3, as 



L. hispinosus. 



The only details given by Catta concerning his species massili- 

 ensis, viz. the nature of the ground on which it was captured 

 " fonds corallig6nes," and the colour, " un beau jaune, tandis- 

 que I'oeil etait completement noir," would seem to point to 

 L. hispinosus.
