There are two males and a small number of females in the collec- 

 tion. The males and females agree with the original description and 

 figures of L. dubia, (Kr<£yer), the inner branch of the uropoda in 

 both sexes consisting of five joints.* 



There are also two specimens in the collection, both females, which 

 have the inner branch of the uropoda two jointed. Although this 

 may be a new species of Leptochelia , I do not feel warranted with 

 such scanty material, and with no males, to describe a new species of 

 this genus.

* There is no character of specific importance to separate L. algicola Harger 

 from L. dubia (Kr^yer) the males and females of L. dubia in the collection from 

 the Bermudas agreeing with Harger's specimens as figured and described, with 

 the exception that the Bermudian specimens have five joints to the inner branch 

 of the uropoda instead of six. Stebbing has pointed out (Ann. Mag. Nat. Hist. 

 (6) xvii, p. 158-159, 1896) that there is some variation in the number of joints 

 in several species of Leptochelia, and L. Edicardsii, which Kr^yer figures and 

 describes as having seven joints to the inner branch, is now recognized as a 

 synonymy of L. savignyi, which is figured and described by the same author as 

 having six joints. It is not improbable, as Stebbing has suggested, that L. 

 savignyi and L. dubia are identical.
