bristle type. Second joint: Ventrally at or somewhat distally of the middle of the joint there 

 is a single short-haired bristle, either pointed or of the tube-bristle type, about as long as this 

 joint or somewhat longer. Third joint: The two bristles are subequal, often about as long as the 

 bristle on the preceding joint, and have short hairs; they are pointed or of the tube-bristle type. 

 Fourth joint: Of the three bristles on this joint the two dorsal ones are often subequal and about 

 as long as the total length of the second and third exopodite joints, the ventral one is somewhat 

 shorter, but theii lengths vary to some extent; they correspond in type to the three bristles on 

 the end joint of the preceding limb. Pilosity: The first exopodite joint is partly furnished with 

 short, fine hairs. Apart from these this limb is usually bare. 



Seventh limb: — The longest bristle is about a third of the length of the shell 

 (for instance in a specimen with a shell about 1,5 mm. long it measured 0,45 mm.). The end 

 joint always seems to be smooth. 



The penis is of the type described by C. ClauS; see this wi-iter, 1891 a, pi. XXII, 

 fig. 11. There is no copulatory appendage; see the accompanying fig. 25. 



The f u r c a (fig. 26, cJ = $) has seven claws. The armature of the claws is moderately 

 strong. There is no verruciform process between the first and second claw. Behind the 

 claws there is (always?) an unpaired short-haired bristle of varying length, sometimes about 

 as long as the second or third claw, sometimes only about as long as the seventh claw. The 

 lamellae are often furnished with groups of short, stiff hairs on the inside. 



The rod-shaped organ (figs. 7 and 8, (J = $) is of about the same type as is 

 described by G. W. MULLER, 1906 a; it is loosely joined to the first antenna by the dorsal bristle 

 on the second joint of this limb. 



Upper lip: — This projects rather slightly; it is roimded anteriorly and has no 

 verruciform swellings (see fig. 1, S = ?)• The exits of the glands of the upper lip are scattered on 

 the antero-ventral side of the lip, but are, however, arranged to some extent in two longitudinal 

 bands, each running on one side of and at some distance from the middle line. The posterior 

 ventral margin of the upper lip is cut off transversally (see fig. 27, ^ — $). Its combs project 

 rather slightly and are furnished with rather numerous and moderately fine hairs. In the inner 

 corner of each of these combs there issue, as in the genus Conchoecia, one or two glands. The part 

 between these combs is in most cases rather narrow, sometimes only slightly more than half 

 the width of the combs, sometimes, however, as broad as them; it is rather deeply concave 

 in the middle; this concavity is sometimes rather broad and rounded as in the accompanying 

 figure, sometimes rather narrow. 



The paragnates are oval ; the hairs on the margin are also fine. The chitinous lists 

 behind the under lip are of the type reproduced by C. Claus, 1874 b, pi. Ill, fig. 26, i. e. they differ 

 from the types developed in both the genera EuconcJioecia and Conchoecia because the _L-shaped 

 posterior part in the latter genera has in Halocypris a backward pointing process at the middle, 

 by which it becomes + -shaped. 



Female: — 



Shell: — Length: According to G. W. MtJLLER, 1906a, „bis 1,85 mm."; according 

 to the same author, 1912, the maximum length for this species is 1,8 mm. The mature females
