Crustacea from Scottish Waters. 33 



pereiopods are slightly notched near the lower front angle, as 

 shown in the drawing (fig. 5). 



The last pair of epimeral plates are broadly rounded and 

 have the posterior margin finely serrated (fig. 8). Uropoda 

 imperfect. 



Telson moderately elongated, the length being about twice 

 the width at the proximal end, and tapering to the somewhat 

 pointed but slightly cleft apex (fig. 9). 



Hah. Station 53 (lat. 59° 36' N., long. 70° 0' W.), 1140 

 metres deep, Aug. 17th, 1906. 



Remarks. — The specimen now recorded has a close general 

 resemblance to E. dolichocarpus, but as it differs from that 

 species in one or two points, I am inclined for the present to 

 regard it as a separate though closely allied species. In 

 E. dolichocarpus the postero-lateral angles of the third pleon 

 segment (the last pair of epimeral plates) " are smoothly 

 rounded, not serrate." In the ' Goldseeker ' specimen the 

 postero-lateral angles are also rounded, but the lateral 

 margin is distinctly serrate. Moreover, in E. dolichocarpus 

 the stern of the fifth joint of the second gnathopods is con- 

 siderably wider than that of the first pair and is nearly two 

 and a half times as long as the part which forms the cup for 

 the propodos, whereas in the ' Goldseeker ' specimen the stem 

 of the fifth joint of the second pair, which differs little from 

 that of the first, scarcely equals in length the part that forms 

 the propodal cup.

One or two specimens of this species occurred in the same 

 gathering in which the Eusirogenes recorded above was 

 obtained. Parascina has a general resemblance to Scina, 

 but differs distinctly in the form of the first and second 

 maxillae and the maxillipeds and in the structure of the fifth 

 pair of thoracic legs. 



The two pairs of maxillae consist of broad lamelliform 

 plates, fringed with numerous fine hairs aud furnished also 

 with several marginal spines, as shown in figs. 11 and 12, 

 PI. II. The maxillipeds consist of two large hemispherical 

 plates, the inner margins of which are nearly straight, while 

 the opposite margins are broadly and evenly rounded but
