Genus Cyclopina, Glaus, 1863. 



Ctclopika geacilis, Glaus. 



1863. Cyclopina gracilis, Glaus (23), p. 104, pi. 10. figs. 9-15. 



A few specimens o£ this small but distinct species were 

 obtained in some material dredged, off East Grlacier, Cape Flora, 

 on July 21st, 1897. Gyclopina gracilis has a wide distribution 

 in the British seas, but is not very common. 



G-enus Thoeellta, Boech^ 1864. 



Thoeellia beu]S]S"ea, BoecTc. 



1864. Thorellia Irunnea, Boeck (5), p. 26. 



Thorellia hrunnea was more or less frequent in several gather- 

 ings of micro-crustacea collected by means of the di'edge, as, for 

 example, in gatherings from West Bay, off East Glacier, and 

 south-west of Elmwood — this last was an inshore gathering ia 

 quite shallow water. 



Genus CruLOPS, 0. F. Muller, 1776. 



CrcLOPS Brucei, sp. n. (PI. 6. figs. 1-6.) 



This appears to be a new species, of which the following is a 

 description: — Length of adult female 1*1 mm. (about ^^g- of an 

 inch). Antennules (fig. 2) moderately short and stout, 12- 

 jointed and sparingly setiferous ; the third and fifth joints are 

 the shortest, the eighth, ninth, and last are rather longer than 

 any of the others except the first. Both branches of the 

 swimming-feet are short and stout and 3-jointed : in the first 

 pair (fig. 3) the inner branches are armed with a strong terminal 

 claw-like spine ; the fourth pair (fig. 4) are less powerfully 

 armed ; the fifth pair (fig. 5) are small, the secondary joint is 

 cylindrical in form, and the length rather more than twice the 

 breadth, the truncate end bears interiorly a moderately short 

 spine, and exteriorly a long seta that is at least four times the 

 length of the joint from which it springs ; the seta that springs 

 from the exterior produced part of the basal joint is also elon- 

 gate. The caudal furca (fig. 6) are nearly three times as long 

 as the last abdominal segment ; the small spiniform seta usually 

 observed on the outer margins of the furca in Gyclops is situated 

 at about a third of their length from the distal end; there is also 

 a minute notch near their base.
