REPOET ON THE SCHIZOPODA. 53 



lobe, pointing forward. Of tlie flagella, the inner one would seem to be very small, 

 whereas the outer is strongly developed. 



The antennal scale is comparatively small, and has no articulation at the extremity. 

 It is oval in form, the apex being rounded ofl', and the outer edge distinctly 

 serrate. 



Of the legs, the two anterior pairs, judging from the figures, would appear to ditt'er 

 somewhat from the rest, their terminal part being a little stronger and more curved. 

 The remaining legs are uniform in structure and not very strong, but have a distinct 

 terminal claw. 



The incubatory lamellae (Fig. 1, ee) were well marked in the specimen examined, and 

 were present, as in the other forms of this family, at the bases of all the legs. 



The caudal limbs would not seem to differ in structure from those of other Lopho- 

 gastrida3. 



The telson is greatly produced, and very narrow, tapering gradually towards the 

 apex, which is acutely pointed ; the lateral edges are almost straight, and in one of the 

 figures appear finely serrate. 



The uropoda are rather large, reaching the tip of the telson, and have both plates, 

 lanceolate, the outer one being somewhat broader, without, however, exhibiting anv articu- 

 lation at the apex. 



Habitat. — The above described specimen was taken in the Southern Ocean, south of 

 Australia. 



Station 158, March 7, 1874; lat. 50° 1' S., long. 123° 4' E.; depth, 1800 fathoms; 

 Olobigerina ooze ; bottom temperature, 33°"5. 



Family II. Eucopiid^. 



Remarks. — This family, so far as at present known, contains but a solitary type, viz., the 

 genus Eucopia, established by Dana for a remarkaljle Crustacean obtained by the United 

 States Exploring Expedition, and named by that author Eucopia australis. This form 

 was classed liy Dana within his division Pen^idea, and Mr. Spence Bate has recently ^ 

 adopted the same view in regard to the systematic position oi the genus. On the other 

 hand, the late Dr. v. Willemoes-Suhm, who rediscovered the same species during the 

 Challenger Expedition, regarded it as the t}^e of a new family of the Schizopoda. But, 

 having apparently not consulted Dana's work, he described the animal us a new form under 

 the name of Chalaraspis unguiculata, and accordingly named the family Chalaraspida;. 

 In my opinion, the view of Dr. v. Willemoes-Suhm, as to the systematic position ^of 

 the present form, is undouljtedly quite correct. The earlier name, however, Eucopia,
