new Crustacea from Devon and Cornwall. 2S5 



(about y'y- of an inch) in lengtli and carrie.1 a single mode- 

 rately large ovisac ; the forehead is produced into a small 

 but distinct rostrum. 



Antennules short, eight-jointed, first and second joints 

 large, the tburth to the seventh very small ; the third and 

 last are subequal and also small, but rather larger than the 

 intermediate joints, as in the formula —

Outer ramus of posterior antennse small and triarticulate. 

 Mandible-palp moderately stout, witli two small branches. 

 ♦Second maxillipeds not very robust, and armed with slender 

 i^longated terminal claws. 



Inner branches (*f first pair of legs slender and considerably 

 longer than the outer branches, the first joint only slightly 

 longer than the last, wdiile the middle joint is rather moro 

 than half the length of the first ; the outer branches reach to 

 near the end of the middle joint of the inner branches. 

 Second, third, and fourth legs also slender; the outer branches 

 of the fourth legs are only slightly longer than the inner. 

 Fifth pair of legs small : primary joint broadly subtriangular, 

 but with the apex truncated and bearing three sette of nearly 

 equal length and one about the same length as the others 

 near the distal end of the inner margin. Secondary brancli 

 moderately narrow, subcylindrical, tapering slightly towards 

 the distal extremity; breadth scarcely equal to half the 

 length; apex slightly produced in the middle to form the 

 base for a slender seta ; a slender seta springs from near the 

 distal end of the inner margin, and there are also about four 

 setaj on the outer margin, the two lower ones being stouter 

 than the others. 



Furcal joiuts very short. 



Jlob. Dredged near Eddystone Lighthouse, Aug. 3 1st, 

 IDOl ; apparentl}'' not common. No males observed. 



The small size of the female, the peculiar structure of 

 antennules, of the first pair of legs, and the form and arma- 

 ture of the last [)air distinguish this from any other known to 

 us. This species has recently b^en observed in dredged 

 material from the Firth of Forth. 



Stenhelia simulans, sp. n. 



Description of the female. — The female of this species has 

 a general resemblance to Stenhelia ima, G. S. Brady. An- 

 tennules eight-jointed, moderately stout, scarcely so elongated
