the first pair is in some respects not unlike tliat of Th. rohusta, 

 Claus, from Nice and Messina f, but the filth pair in form 

 and armature is decidedly different. It may be further 

 remarked that the structure of the first pair of feet in both of 

 tlie species named exhibits a close resemblance to that of the 

 first pair in certain species of Dactyhpus, so that the species 

 may be almost considered a connecting-link between the two 

 genera Thalestris and Dactylopus. 



Genus PSEUDOTHALESTKIS, G. S. Brady, 1883. 

 P seudoihaleatris major (T. & A. Scott). 



1895. Psetcdoivestwoodia major, T. & A. Scott, Ann. & Mao-. Nat Hist. 

 (6) vol. XV. p. 66, pi. vi. tigs. 17-30. ° 



This small species was moderately frequent in a gathering 

 collected between tide-marks at "Vadso ; but it was not 

 observed in any of the other Finmark gatherings. 



Four British species of Pseudothcdestris have been de- 

 scribed—the first in 1894 in the Twelfth Ann. Report of the 

 Fishery Board for Scotland, pt. iii. p. 257, pi. xi. tigs. 21-29, 

 under tbe name of Paeudoioesticoodia Andrewt, T. Scott: 

 descriptions of other two species by T. & A. Scott were 

 publislied in the Ann. & Mag. Nat. Hist, for January 189 5 

 under tiie names of Pseudoivesticoodia ]>ygmaia and major ; 

 in the 'Annals' for tlie iollowing month of June (p. 463) 

 these authors withdrew the name Pieudowestwoodia, T. Scott, 

 in favour of Pseudothalestris, G. S. Brady, as it was found 

 that the two genera were identical and that the latter name 

 had been published several years before the other. The 

 description of the fourth species by Prof. G. S. Brady was 

 published early in 1901 in Nat. Hist. Trans. N. D. & N. C. 

 vol. xiv. p. b'd, pi. iii. figs. 11-16, under the name of Pseudo- 

 thalestris monensis^ from specimens obtained at Port Erin, 

 Jsle of Man. Pseudothalestris major has not previously been 

 recorded from the Arctic seas. 



Genus Westwoodia, Dana. 

 * Westwoodia nohilis (Baird). 

 1845. Arpacticus nobilis, Baird, Trans. Berw. Nat. Club, vol. ii, p. 155. 



This pretty little species resembles very closely the British 

 species of Pseudothalestris, but differs distinctly in the 

 structure of the first pair of thoracic feet. It was of rare
