]()l)e, i)ointing forward. (_)f tlif Hagella, the iniici- oiu- Wduld scciii to I)e very small, 

 wliereas the outer is strongh^ developed. 



The antenna! scale is cdnniarativelv small, and has nn articulation at the extremity. 

 It is oval in form, the apex being rounded off. and the outer edge distinctly 

 serrate. 



Of the legs, tlie two anterior pairs, judging from the figures, would appear to differ 

 somewhat from the rest, their terminal ])art l)eing a little stronger and more curved. 

 The remaining legs are uniform in structure and not veiy strong, hut hav(> a distinct 

 terminal claw. 



The incubatory lamella? (Kig. 1, ce) were well marked in the s[)ecimen examined, and 

 were present, as in the other forms of this iamily, at the ba.ses of all the legs. 



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

 gastridai. 



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

 a})ex, which is acutely pointed ; the lateral edges are almost straight, and in one of the 

 figures ajspear finely serrate. 



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

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

 lation at the apex. 



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

 Australia.

Family II. EucopiiD,^. 



liejiiark/^. — This family, so far as at present known, contains but a solUar\' t\pe, viz., the 

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

 States Exploring Expedition, and named l)y that author Eucopia aunindi:^. This form 

 was classed l)y Dana within his division Penseidea, and Mr. Spence Bate has recently ' 

 adopted the same view in regard to the systematic jjosition of the genus. ( )n the other 

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

 ( 'hallenger Expeclition, regarded it as the tjV^ ^f a new family of the Schizopoda. But, 

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

 the name of Chalaraspis iinguiculata, and accordingly named the family Chalarasjtidje. 

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

 the present form, is undoubtedly quite correct. The eailier name, however. Eucopia,
