rounded, the denticle 011 the outer edge veiv Mnall. Tth pair of 

 legs rather shorter than the preceeding. Telson with l pairs of 

 dorsal denticles. the apex very much narrowed and provided (dose 

 to the tip with two pairs of small lateral denticles; subapical 

 spines scarcely surpassing the apex, smooth. Uropods shorter than 

 the telson; inner lamella very slightly surpassing the outer. Length 

 of the largest specimen: 24 mm. 



Hab. Pacific Ocean on two different localities (off Kandavu 

 Fiji isl. and North of Australia). 



Bemar/.s. I have had soine douht in referring this form to 

 the typical species established by M. Edwards, as neither the 

 veiv strong dorsal spine on the t hird postabdoniinal segment, nor 

 the peculiar flattened spine of the carapax behind the rostrum is 

 represented on the figure given in M. Edwards' work. < m the 

 other hand the figure shows distinctly another feature very 

 characteristic of the species in question and not found in any other 

 form known to me, viz the peculiar shape and anterior curvature 

 of the two anterior pairs of postabdominal epimera. The specimen 

 originally examined by M. Edwards was from the North Atlantic, 

 while all the '('ballenger' specimens have been collected in the 

 Pacific ocean. ( !onsidering however the vvide geographical distribution 

 of some species of Euphausiidæ, tliis circumstance does not seem 

 in my opinion to prevent an identification of the 'Challenger' spe- 

 cimens with the form described by M. Edwards. 



25. Thysanopoda obtusifrons n. sp. 



Form of body somewhat robust, not much compressed. Carapax 

 without any lateral denticles or dorsal keel. frontal part slightly 

 produced, but blimt ly rounded. not forming any distinct rostrum. 

 Postabdominal segments smooth above, the epimera of moderate 

 size. none of them anteriorly curved. 2nd, 3th and 4th somewhat 

 sinuated at the inferior margin. Last segment longer than the 

 preceeding; præanal spine obsolete. Eyes rather small, scarcely 

 exceeding the sides of the carapax. Antennular peduncle very
