frequent in one or two o£ the Frauz-Josef Land gatlieriugss, 

 i. e. in a gathering dredged about fifty yards off West Point, 

 Gape Flora, in 2 to 3 fathoms, on June 18th, 1897 ; in another 

 from West Bay, dredged in about 8 fathoms on July 5th, and 

 in a third collected on the 23rd or 24th of the same month. lu 

 some of the specimens there is a tendency for both branches of 

 the fifth thoracic feet to have pellucid markings along the edge 

 of the outer margin.

This species was obtained amongst sand near East Glacier, 

 Cape Flora, August 5tb, 1896 ; it appeared to be rare. D. coro- 

 natus was described and figured in Part iii. of the Twelfth 

 Annual Eeport of the Fishery Board for Scotland (1891).

 Several specimens of what seems undoubtedly to be this 

 species were obtained in a gathering of small Crustacea collected 

 off West Point, Cape Flora, in from 2 to 4 fathoms of water, on 

 July 21st, 1897. D. tenuiremis is closely related to the next 

 species, but differs from it in the form of the fifth thoracic feet, 

 and in the structure of the first pair, as shown by the figures. 



Dacttlopus low giro stius, Claus. (PI. 3. figs. 5-8.) 

 1863. Dadylopus longirostris, Claus (23), p. 127, pl. 17. figs. 4-6. 

 This is one of the species described by Dr. Claus in his ' Die 

 freilebenden Copepoden ' (pub. 1863), which were obtained in 

 the vicinity of Heligoland. It resembles D. tenuiremis in some 

 respects, but the form of the fifth thoracic and especially of the 

 secondary joints is distinctly different ; these outer (secondary) 

 joints are in this species broadly oval and leaf-like (" das aussere 

 ovale Blatt "), the proportion of the breadth to the length being 

 nearly as 20 is to 29, whereas in D. tenuiremis it is nearly as 

 15 is to 28 ; there is also a difference in the general outline as 

 well as in the armature of both the basal and secondary joints 

 of the fifth pair. It may be noted further that, besides the 

 difference in the first swimming-feet already referred to, the 

 structure of the posterior foot-jaws differs slightly in the two 

 species, as indicated by the figures. D. longirostris occurred in a 

 gathering from the vicinity of East Glacier, Cape Flora ; only a
