triangular densely setose process. The vermicular appendage* and 

 abdominal lamina are precisely as in the female. 



Hab. Greenland ( S & $ )» Shetland ( $ ), Norway, North Sea 

 off Northumberland coast ( $ ), Bay of Biscay ( d ). 



I think there can be little doubt, from anatomical characters taken 

 together with the agreement in shell- form, that Fischer's species is 

 simply the male of the better-known form ; the exactly similar 

 spinous armature of the vermicular appendage is very striking, so 

 large a number as twenty-eight or thirty spines being met with, as 

 I believe, in no other instance.

 ?$, Norman, 1861. 



Philomedes interpuncta, $ , Brady, 1868. 



Female. Carapace much more rounded and more tumid than that 

 of the male, and rather smaller ; seen from the side subelliptical, 

 highest in the middle ; superior and inferior margins both strongly 

 convex ; posterior extremity obliquely truncate, and bearing at the 

 angles two distinct and sharp backwardly projecting convergent 

 spines ; height equal to two-thirds of the length. Seen from above 

 regularly ovate, widest in the middle ; width equal to about half the 

 length ; mucronate behind, obtusely acuminate in front. Superior 

 antennae short and stout ; setae short and subequal ; natatory branch 

 of the inferior antenna having its setae exceedingly short, secondary 

 branch indistinctly Particulate, the first joint bearing three setae 

 (one of which is of moderate length and plumose) on its outer mar- 

 gin, second joint having one marginal and two very minute terminal 

 setae. Length -pig- inch. 



Hab. Norway, west coasts of Scotland and Ireland, Shetland, 

 Northumberland coast, Plymouth Sound, Channel Islands, Fosse de 

 Cap Breton. 



The only places where the female has been found are Cap Breton 

 and Loch Long in Scotland, in the last of which localities both sexes 

 were dredged in considerable numbers, at a depth of 4-10 fathoms, 

 by my friend Mr. D. Robertson. The Scottish specimens are smaller 

 than those from the Bay of Biscay, but in other respects present the 

 same characters. 



* The term " oviferous foot' - seems scarcely applicable to this limb, as it 

 exists in the male in precisely the same degree of development as in the female.
