the inner extending a little farther. Antennal scale narrow, elongate, 

 flagellum two-thirds as long as the body. External raaxillipeds with 

 the distal joints hairy, and exceeding by half their length the an- 

 tennal scales. First pair of feet much as in C. vulgaris, the carpus 

 with a spine on each side below. The occludent margin of the hand 

 very oblique. Second and third pairs of feet slender, the second 

 chelate and a little shorter than the third ; fourth and fifth pairs elon- 

 gate cylindrical, the dactyli styliform. First five joints of the abdo- 

 men with a median carina, the sixth and telson with two carinal tel- 

 son elongate, sides straight, tip acute. 



Length two inches.

I insert for comparison figures of C. vulgaris (pi. I, fig. 5), C. boreas 

 (pi. I, fig. 6), and C. franciscorum (pi. I, fig. 7).

I have examined numerous specimens of this species from the east 

 and west coasts of America and from Europe, and fully agree with 

 Professor Smith in uniting with it the form formerly known as C. 

 nigricaiida. Specimens in the Peabody Academy from Beverly, Mass. 

 (No. 138) have the sixth and seventh abdominal segments sulcate above 

 as in the majority of the west coast forms. Kinahan's figures (Proc. 

 Roy. Irish Acad., viii, pi. iv, 1864) are verj' incorrect. The second pair 

 of feet are greatly larger than in any specimens I have seen, and 

 the joints of the external maxillipeds are wholly unlike those found in 

 nature.

This is probably to be found in North American waters ; there are 

 specimens in the museum of the Philadelphia Academy without local- 

 ity, but which came with other American forms {Paracrangon echi- 

 natus, Hipjmlyte prionota, etc.). Its origiflal locality, Karatschatka, 

 would seem to favor this idea.

 compiled. 

 This Australian species must be renamed, the term intermedius hav- 

 ing been used in 1860 by Stimpson for a species from Behrings Straits. 

 Mr. Bate is rather unfortunate with the species described in this paper,
