Phyllodurus abdominalis Stimpson.

1857. 



Of this interesting and imperfectly known form a large series 

 of both sexes and different stages of growth was obtained. 

 These it is proposed to describe in detail in a later paper. It 

 may be mentioned that the male of this species was recorded 

 and briefly described by Lockington in 1876, in a paper whose 

 title affords no clue to this part of its contents (** Descr. of a new 

 gen. and sp. of Decapod Crustacean," Proc. Calif Acad. Sci. 

 (1876), 1877, p. 57).

Of the species described in Budde-Lund's Monograph our 

 specimens approach most closely in the proportions of the uro- 

 pods to L. Pallasii Br., from which they differ only in the 

 much narrower body. Stimpson, however, mentions that the 

 relative width of the body is subject to great variation. The 

 L. septentrionalis of Lockington (Proc. Calif Acad. Sci. (1876), 

 1877, p. 46), a species not mentioned by Budde-Lund, agrees 

 with our specimens so far as the short description goes, but its 

 distinctness from L. Pallasii does not appear to be beyond doubt. 



The dimensions of our two specimens are as follows :
