Here I may perhaps insert a few remarks on an adult female 

 captured by the Siboga (stat. 143). It measures 42™™ in length 

 and cannot be referred to any of the four above-named species, 

 but it is, unfortunately, in a bad state of préservation, and a 

 spécial investigation must be postponed. Yet it can be pointed 

 out that the front margin of the carapace is considerably more 

 convex than in E. australis or E. unguiculata, agreeing well 

 with fig. i3 on Pl. x in the Challenger Report (which repre- 

 sents the maie belonging to E. sculpticauda or E. intermedia); 

 the eyes are essentially terminal, and their stalks decidedly 

 longer than in E. unguiculata. 



Katerythrops Oceanse, Holt & Tatt. 



Katerythrops Oceauœ, Holt & Tattersall, op. cit. p. 117, 

 Pl. xx, p. 143. 



Localities. — Stat. 1844, 2 spécimens; stat. i85i, 1 spé- 

 cimen. 



Remarks. — My largest spécimen, a female with marsu- 

 pium, measures 8 mm in length. — The British authors quoted 

 mention only two spécimens taken west of Ireland. 



Euchœtomera Fowleri, Holt & Tatt. 



Euchœtomera Foivleri, Holt & Tattersall, op. cit. p. 123, 

 Pl. xxiv, fig. i-3, p. 144. 



Locality. — Stat. 1 78 1 , 1 spécimen. 



Remarks. — The spécimen is a maie; it has two very long 

 setas inserted on the prominences on the end of telson mentioned 

 by the British authors. The fine species has been established on 

 spccimens from the Bay of Biscay.
