Protomedeia (?) Whitei, Bate. In the same locality as the 

 last. 



Melita obtusata (Montagu) =M. proximo,, another form of the 

 male, and Megamcera Alderi, the female. In Ardbear Bay 

 (4 fathoms) on Laminaria saccliarina. Also many speci- 

 mens of both sexes nestling between the tentacles of A nthea 

 Cereus, in Ardbear Bay — a strange and, one would have 

 thought, a dangerous habitat.

Genus Exunguia*, Norman, n. g. 



Antenna? short and strong ; flagella rudimentary, upper 

 pair without a secondary appendage. Body wide; coxa? 

 shallow. First gnathopods long, slender, filiform ; dactylos ob- 

 solete. Second gnathopods subchelate, slender, but yet much 

 stouter than the very delicate first pair. Pereiopods rather 

 short, subequal ; propodos longer than carpus. Uropods all 

 two-branched ; branches short, simple. Telson squamiform. 



This genus seems to be most nearly allied to Cratippus, from 

 which it is distinguished by the remarkable character of the 

 first gnathopods. 



Exunguia stihpes, Norman, n. sp. PL XXII. figs. 7-12. 



Head produced into a short rostrum between the upper an- 

 tenna3. Eyes on a process between the upper and lower an- 

 tenna?. Antenna? of both pairs subequal, strong, but short, 

 equal in length to first 3-4 segments of body ; joints of 

 peduncle subequal to each other in length, but each rather 

 shorter and of less diameter than the preceding, round, smooth, 

 except one or two minute spines on the inner margin ; flagella 

 rudimentary, scarcely a third of the length of the last joint of 

 peduncle, composed of three or four excessively short articu- 

 lations. First gnathopods slender and filiform, basos long and 

 slender, more than equal in length to ischium and metacarpus 



* From ex and unguis, without a nail.
