20 Canon A. M. Norman — Notes on the 



the secondary branches of the fifth pair are narrow and sub- 

 cylindrical (fig. 6, PL III.)- 



The antennules (fig. 20, PI. II.), which resemble very closely 

 those of C. varians, are short and moderately stout, and com- 

 posed of five joints, the penultimate joint being very small, and 

 they are also sparingly setiferous. The antennae and mouth- 

 organs are apparently similar in structure to the same 

 appendages in Scottish specimens of Cletodes tenuipes; so 

 also are the first pair of thoracic feet (fig. 4, PI. III.). In 

 the next three pairs the inner branches, as already remarked, 

 are rather smaller, and the secondary branches of the fifth 

 pair are also slightly different ; but these differences do not 

 appear to be of suflicient importance to be of specific value.

1899. Cletodes j^erplexa, T, Scott, Seventeenth Ann. Rep. Fishery 

 Board for Scotland, pt. iii. p. 257, pi. xi. tigs. 12-20, pi. xii. tig. 1. 



This curious species occurred very ^Daringly in a gathering 

 from Bog Fiord, the only one in which it w'as observed. 

 G. perplexa, which has not till now been recorded out of 

 Scotland, is readily distinguished by the form of the fifth 

 thoracic feet, and that even without dissection. 



Cletodes lata, T. Scott. 



1892. Cletodes lata, T. Scott, Tenth Ann. Rep. FisheiT Board for Scot- 

 land, pt. iii. p. 257, pi. X. tigs. 10-18. 



The gathering in which this species was obtained was 

 collected in Klosterelv Fiord. 1 find no previous record of 

 this Cletodes from the Arctic seas. In general appearance it 

 is not unlike Cletodes similis, but it differs from that species 

 in some details of structure, and especially in the form of the 

 fifth thoracic feet in the female.

1895. Cletodes similis, T. Scott, Thirteenth Ann. Rep. Fishery Board 

 for Scotland, pt. iii. pi. iii. figs. 22-26, pi. iv. tigs. 1-3. 



This species was observed in a gathering from Svolva}r, 

 Lofoten islands, the only gathering in which it was noticed. 

 It is one of the species collected by Mr. Bruce at Franz-Josef 

 Land and also to the eastward of Spitzbergen. Only one or 

 two specimens occurred in the Svolva^r gathering.
