 {With 2 Plates.)* 



Preliminary Note. 



The Crustacea described here were obtained in collections made by 

 the Fishery steamer " Goldseeker " while carrying on work in the 

 North Sea and adjacent waters under the direction of Professor 

 d'Arcy W. Thompson, C.B., F.L.S., the representative for Scotland 

 on the International Committee. I am indebted to Professor 

 Thompson for permission to publish these notes. 



Hemilamprops normani, Bonnier. 



1876. Hemilamprops normani, Bonnier, Campagne du "Caudan," 

 Edriophthalmes ; Ann. l'Univ. de Lyons, p. 546, PI. XXXIX., 

 fig. 3. 



Several specimens which agree very well with Bonnier's 

 description and figures of II, normani were obtained in deep-water 

 gatherings from "Goldseeker" Station 53 (Lat. 59°36 N., Long. 

 7°0 W.), and others from a gathering collected in Lat. 59°25 N., 

 Long. 7° 33 W. The telson is moderately stout, rather shorter than 

 the peduncle of the uropods, and with the lateral margins finely but 

 distinctly serrated throughout ; the distal half of the telson is also 

 furnished with about seven pairs of stiff lateral spinules, and with five 

 similar spinules at the apex, the middle one being distinctly longer 

 than the others. The length of the entire specimen was about 

 8 mm., and therefore rather smaller than the size given by Bonnier. 



This species has a resemblence to H. cristata, G. O. Sars, which 

 was also not uncommon in the " Goldseeker " collections, but was 

 readily distinguished from it by the difference in the armature of the 

 telson. 



Diastylis serricauda, sp. n., 5, PI. I., figs. 1-4. 



In its general appearance this species resembles D. longipes, G. O. 

 Sars. The cephalothorax is moderately elongated and equal to rather 

 more than half the entire length. The cephalon seen from the side 

 appears to be of an oval form, and on the dorsal aspect, especially 

 towards the front, are a number of stiff spinules ; the rostrum is 

 narrow and somewhat produced in the median line, and the pleon
