EUEOPEAN FOEMS OF THE CIllOLATSiyjE. 361 



as since 1890 the species has been secured twice in England. 

 I therefore now think that my specimens were captured some- 

 w^here in the eastern part of the Atlantic, on the way from 

 Denmark to St. Thomas. Stebbing (1895) has discovered 

 E. spinigera at Ilfracombe, at the entrance of the Bristol 

 Channel, and his remarks as to its characters prove the cor- 

 rectness of the determination. In 1903 Canon A. M. Norman 

 told me in a letter that he the same summer had captured this 

 species at Plymouth. Finally, A. 0. Walker & J. Hornell 

 (Journ. Marine Zool. ii. p. 51) record it from the Channel Islands, 

 but as they add the erroneous remark, " probably identical with 

 E. truncaia, Norman," the determination is, in my opinion, less 

 trustworthy. 



Semarhs. — This rather large species is easily separated from 

 all other forms by the highly-developed armature of the thoracic 

 segments and by the shape and armature of the posterior margin 

 of abdomen.

Process from clypeus large, seen vertically from below covering 

 at least the major part of the area between the mandibular 

 palps. 



Antennulse. — Male : Peduncle strongly thickened, nuich thicker 

 than in the female, but third joint shorter than in that sex, 

 about as long as second joint; flagellum reaches the anterior 

 lateral angle of thorax, its first joint is thickened, especially 

 towards the base, compressed and furnished with an immense 

 number of very long sensory hairs, while the four other joints 

 are very short, and their combined length is more than three times 

 shorter than first joint ; one of the terminal setae is somewhat 

 longer than these four distal joints together. Female : of normal 

 size ; third joint of the peduncle a little longer than the second ; 

 flagellum reaches to the anterior lateral angle of thorax, its first 

 joint is somewhat shorter than in the male, less compressed, 

 scarcely thickened, with a moderate number of shorter sensory 

 hairs, more than three times longer than the remaining joints 

 together ; terminal setae short.
