hito a tooth, iiitcrnally concave. Pereiopoda having tlie dactylos 

 crcnuhited upon the flexible side, and tei'minatiug in a curved 

 shaip point. The i)cniiltimate pair of pleopoda have the rami 

 nearly equal in length. Telson lanceolate.

I received this species from my kind friend Mr. George Barlee, 

 who took it with the di'cdge at St. Ives, on the north coast of

Eyes round. Superior antennae as long as the inferior. Inferior 

 antennae having the peduncle not longer than the peduncle of the 

 superior. Fii'st paii' of gnathopoda ha-s-iug the carpus broader 

 than the propodos, and not inforiorly produced ; propodos broader 

 at the palm than near the carpus; j)alm not oblique; inferior 

 angle broadly rounded ; dactylos longer than the palm. Second 

 pail' of gnathopoda having the propodos naiTow ; the palm ex- 

 tremely oblique, almost parallel ^dth the superior margin, cui-ved 

 at the inferior angle, with a sharp denticle : a small denticle exists 

 on the palm near the base of the dactylos. Telson rounded. 



The above description is taken from Kriiyer's figure, which I 

 have also copied, not ha%'ing seen a specimen of tlie species.

Eyes small. Superior antennae longer than the inferior. Inferior 

 antennae having the peduncle considerably longer than the pedun- 

 cle of the superior. First paii' of gnathopoda having the meros 

 produced inferiorly, terminating obtusely, and ciliated ; the carpus 

 longer than the propodos, and not produced inferiorly, ciliated ; 

 propodos very long, and ciliated superiorly and inferiorly towards 

 the extremity ; palm inappreciable ; dactylos very short. Second 

 pair of gnathopoda having the propodos quadi'ate, a little broader 

 at the palm than posteriorly ; pahn slightly convex and ciliated, 

 armed at the inferior angle with a strong tooth. 



I have not seen any specimen of this species ; the description is 

 therefore dependent upon the acciu'acy of M. Krover's draMang, 

 which is also repeated.
