 Normandy (Jeffreys) ; Tenby (Mr. Webster). A species found at

Eyes round, moderately large. Superior antennae two-thirds as long 

 as the animal ; peduncle short, scarcely longer than the cephalon, 

 third joint small ; flageUum nearly five times as long as the pe- 

 duncle. Inferior antennae scarcely half the length of the superior ; 

 peduncle extending beyond the peduncle of the superior by nearly 

 the length of the last joint ; flagellum but little longer than the 

 last joint of the peduncle. First pair of gnathopoda very smaU : 

 second very large, having the cai-pus short ; propodos long-ovate, 

 upper margin arcuate ; palm very oblique, straight, continuous 

 with the inferior margin, defined by a slight eminence ; dactylos

Hah. Found by M. Hejiiauu in the Atlantic Ocean, lat. 28° N. 

 (near the Canary Isles) (Ediuarch) ; Gulf weed, Atlantic Ocean 

 (Goodsir). 



Having compared Goodsir's figure with the type in the collection 

 of the .Jardin des Plantes, 1 have no doubt of their identity.
