There is only a t'cmnle in the Collection of the Biitish ^luseum ; 

 but the great length of the superior nntennce have induced me to 

 place it in this genus rather than in Talitrns. It may be the 

 female of the Orchestia that Krauss supposed to be 0. BoiUe.

Upper antennje reaching beyond the extremity of the penultimate 

 articulation of the peduncle of the inferior antennae, which is 

 about half the length of the ultimate. Lower antennse about half 

 the length of the animal, and the flagellum about haK the length 

 of the antennae. First pair of gnathopoda in the male having 

 the propodos much shorter than the carpus ; the palm is nearly at 

 right angles with the length of the propodos ; the limb is covered 

 with many short hairs. Second pair of gnathopoda in the male 

 having the propodos developed into a broad stout hand, the palm 

 of which is fui-nished with two large teeth, stout and pointed. 



Length y|ths of an inch. 



In Dana's figure the teeth on the palm are given longer and shghter 

 than in the specimens in the Paris and British Museums. One tooth 

 is not far from the joint of the dactylos, the other antagonizes with 

 the extremity of the dactylos. The female is not kno^Ti.

4. Talorchestia poUicifera. 



Orchestia pollicifera, Stimpsoti, Proc. Acad. Nat. Sci. 1855. 



" Male. — "With stout inferior antennae, the flagella of which form one- 

 third of their length. First pair of gnathopoda small, chelate, with 

 the penult and antepenult articulations produced below into thumb - 

 like processes ; second pair with ovate hands of moderate size. 



" Female. — With slender inferior antennae ; flagella 12-articulate ; 

 superior ones as long as the first two joints of the others. First 

 pair of gnathopoda simple ; second paii" with small hands, having 

 a minute lateral finger. Colour pale brownish ; eyes rather small, 

 round, black. Caudal stylets short ; rami subeonical. 



" Length three-fifths of an inch. 



" Hah. Loo Choo." (Stimpson.) 



We have not seen this species ; but the fii^st pair of gnathopoda 

 being simple places it in this genus.
