CLETODES. 93 



two, terminal setse (figs. 16 and 17), the first joint 

 minute ; marginal spines of the outer branches slender 

 and plumose. Fifth foot in the female (fig. 18) folia- 

 ceous, the distal joint long, bearing two long setae at 

 the apex, two on the outer, and one on the inner 

 margin, basal joint small, with three internal and one 

 external setse (fig. 12). Length -^n.d of an inch ('79 

 mm.) 



Several specimens were found amongst dredged 

 material, from a depth of five fathoms off Hartlepool, 

 and one or two from 7 29 fathoms off Portincross, 

 Ayrshire. 



M. Boeck's description of Cletodes laticauda may 

 very possibly be meant to apply to this species, but 

 his account of the first pair of feet and of the caudal 

 segments does not agree accurately with my own 

 observations of those organs in 0. longicaudata, and it 

 seems, therefore, best to adhere to the name already 

 proposed by Mr. Robertson and myself.* 



* I leave the descriptions of the two species C. longicaudata and 

 C. limicola as originally written, but must express some doubt as to 

 their entire accuracy. That two distinct species are referred to I have 

 no doubt, but as they occur mixed up together in the same gatherings, 

 and are not readily distinguishable except when quite perfect, it is quite 

 likely that there may be some confusion between the two. The dis- 

 tinctions of sex especially, and of the fifth pair of feet, I have not been 

 able quite clearly to make out.
