S fecial terminology: — First antenna: — For the five bristles on the two distal 

 joints I have used the same alphabetical notation in this genus as I did for the genus Halocypris 

 above. Thus the two bristles of the next to the distal joint are denoted by a and b; here in 

 the male the hyaline sensorial filament is denoted as the a-bristle, the long, ordinary bristle 

 as the b-bristle. The disto-anterior of the three bristles on the end joint is denoted as the e-bristle, 

 the two others as the c- and d-bristles, the long ordinary bristle in the male being denoted as 

 the d-bristle, the remaining one, the hyaline sensorial filament, as the c-bristle. 



Mandible: — As in the case of the genus Halocypris so in this genus the bristles 

 denoted by C. Claus as ,,Stachelzahne" are termed lancet-bristles. 



Fifth limb: — Those of the bristles on the first exopodite joint that are situated 

 medio-ventrally, in most cases somewhat proximally of half the length of the joint, are called 

 .,the medio-ventral bristles", the ventral group of bristles at or somewhat proximally of half 

 the length of the joint are called ,,the proximo-ventral" bristes and the ventral group near the 

 distal boundary of this joint are termed ,,the disto-ventral" bristles. 



Rod-shaped organ: — The distal part of this organ, which is, at least in the 

 males, in most cases well marked off, and which is called by (1. W. MOllbr ,,Endstiick", is 

 called in the present work ,,capitulum", after the example of G. S. Brady and A. M. NORMAN. 

 The part situated proximally of the capitulum is called the shaft. 



Spinifera group G. W. Muller 



(= Paraconchoecia [part.] C. Glaus). 



Number of species. G. Claus, 1891a, included in the genus Paraconchoecia, besides the species Conchoecia 



oblonga dealt with below, the following species: 



Conchoecia sfinifera, (C. Claus), 1891 a, p. 64; pi. X. 

 inermis, „ ,. 1891 a, p. 65; pi. XI. 



„ gracilis, „ „ 1891 a, p. 66; pi. XII. 



All these species, except C. gracilis, which appeared to be a synonym of C. elegans 

 G. 0. Sars, are included by G. W. Muller, 1906 a, in the Spinifera group established by him. 

 In addition this writer adds the following species to this group in the work just mentioned:

 „ echinata, ,, ,, ,, 1906 a, p. 61; pi. X, figs. 14 — 24.
