the inner margin, while the third joint bears only two terminal 

 spines^ the inner one stout and about twice as long as the 

 oih(r. Fitth pnir very small ; each foot consists of a single 

 joint \\hich bears 1^vo small terminal setae. 



The abdomen is moderately slender and composed of four 

 segments ; the genital segment is somewhat dilated and 

 about equal in length to next three segments taken together; 

 the second and third segments are small, while the fourth is 

 rather longer than the preceding one. 



The furcal joints are about twice as long as the last abdo- 

 minal segment; each joint is furnished with several terminal 

 seta', and a single small bristle springs from near the middle 

 of the outer edge. 



IJah. Taken in Plymouth Sound, among Ilydrozoa &c., 

 near low-water, in August 1! 03 ; rare. 



This small species resembles a diminutive Pseudanthesshis 

 gracilis, but the structure of the fourth ])air of thoracic legs 

 shows that its relationship is with Canu's genus Uernnann- 

 ella. It differs, however, from any llernnannella hitherto 

 described by the form of the mandibles, the proportional 

 lengths of the abdominal and furcal joints, and one or two 

 other points mentioned in the description.

Gymnocypris Waddellii. 



Pharyngeal teeth 4 : 3 — 3 : 4, cylindrical, obtusely pointed, 

 slightly incurved. Depth of body about 5 in the length, 

 length of head about 4. Breadth of head about If in its 

 length, diameter of eye 6-8, length of snout 3^-3]r, inter- 

 orbital width 3-3-^. Sncut obtuse; mouth terminal, oblique ; 

 anterior edge of upper jaw not below tlie level of the lower 

 margin of eye ; maxillary nearly reaching the vertical from 

 the anterior margin of eye. 10-13 gill-rakers on the lower 

 part of the anterior arch, 2 or 3 on the upper part. Dorsal 

 111 8, its origin a little nearer to tip of snout than to base 

 of caudal ; third simple ray slender and articulated above, 

 slightly thickened and finely serrated in its basal half (in 

 the two smaller examples), or not serrated (in the two larger 

 ones). Anal III 5, extending to the base of caudal when 

 laid back. Origin of ventral below about the middle of dorsal.
