two-thirds of the length of the hody; the peduncle slightly 

 compressed dorso-ventrally, the two last joints nearly equal in 

 length, longer than the others ; flagellum composed of about 

 twenty articuli. Length If in.

Allied to /. elongata, Miers, but having the thorax very much 

 broader in proportion to the length. 



Fam. SPHJEKOMIDiE. 



Genus Cilioea, Leach. 



The following four species together with two described in the 

 first part of this paper all agree with the Ciliccea Latreillii, of 

 Leach in having the penultimate segment of the abdomen pro- 

 longed, at least in the males, into a process or spine, in having 

 the last segment dilated anteriorly, and more or less excavate at 

 the apex — the excavation being with or without a central lobe — 

 and in having the outer ramus of the uropoda incapable of folding 

 under the inner. Of these C. tenuiccmdata, C. crassicandata and 

 C. crassa agree with one another and with Leach's species, and 

 differ from the other three, in having the immobile ramus of the 

 uropoda rudimentary ; but C. crassa again differs from C. tenui- 

 caudata and C. Latreillii, and agrees with the other species 

 mentioned, in having a mesial lobe in the centre of the posterior 

 abdominal notch. Such differences are regarded as of generic 

 value in this family, but for the present I prefer to retain all the 

 species mentioned in the genus Ciliccea — the common characters 

 afforded by the produced abdominal segment and other points 

 constituting them a sufficiently natural group.
