Marine Copepoda 29 K 



The fifth foot resembles that of the type, but the marginal seta are uni- 

 formly longer than in the figure by Sars (Fig. 38).

Fig. 38. Pseudobradya minor. 

 Fifth foot of female. 



The form here described differs slightly from the typical Ps. minor in 

 certain proportions, somewhat as Ectinosoma neglectum differs from E. sarsi. 

 In the gathering from station 27 t, u, (see remarks under Table IV) there was 

 another Pseudobradya, of 0-86 mm., caudal setae 0-51 mm., which may be 

 the Ps. acuta of Sars. It comes very near to Ps. acuta by its rostrum, p 5, and 

 furca; but in p 5 the appendicular seta arises near the base of the distal joint, 

 whereas in acuta Sars describes and figures it as issuing from the basal joint. 



In Ps. minor Sars mentions the caudal setae "not much elongated". In 

 Ps. acuta the caudal setae are "slender and elongated". Sars obtained only 

 two examples of Ps. acuta, in company with Ps. minor, at Selven, Trondhjem 

 Fiord. A similar origin of the appendicular seta from the basal joint was 

 figured by T. Scott for Ectinosoma finmarchicum, wherein this species would 

 differ from E. elongatum Sars, which was also found only at Selven in 3-6 fathoms, 

 on muddy sand. The value of the appendicular seta as a diagnostic feature 

 seems not to be fully established. 



25. Harpacticus superflexus, n. sp. 



This species resembles H. flexus Brady in all but size and the shape of the 

 finger of the posterior maxilliped.

Length of female, 1-20 to 1-26 mm., of male, 1-04 to 1-12 mm.; caudal 

 furca a little longer than anal segment, caudal setae, 0-65 to 0-69 mm., some- 

 times shorter in the male. Urosome stout, barrel-shaped; caudal rami parallel, 

 as broad as long, spinose distally. The body in the preserved state is often 

 transparent. The cephalosome has a polished convex dorsal surface; the 

 remaining segments of the thorax are smooth, with a metallic lustre, and groups 

 of small dark spots on the pleurae.
