Synalpheus brevicarpus (Herrick), variety ? 
Alpheus saulcyt var. brevicarpus Herrick, Mem. Nat. Acad. Sci., V (1891), 
p. 383. 
Synalpheus brevicarpus Coutiére, Proc. U. 8. Nat. Mus., XXXVI (1909), 
p. 50, text figs. 29, 30. 
Okra Reef, Barbados, May 13; four specimens. Pelican 
Island, Barbados, May 13; one specimen. 
These specimens in many ways seem to represent S. minus 
antillensis, but having the S. brevicarpus guerini rostrum and 
lacking a spine on the upper angle of the basicerite, it seems 
that they had best be considered as a variety of S. brevicarpus. 
In this connection I have examined specimens in the eollee- 
tions of the U.S. National Museum determined by Prof. Cou- 
tiére. It appears that some of the specimens labelled S. minus 
have the basicerite more as in his figure of S. brevicarpus 
guerini, and that in the specimens of the type lot of the latter, 
that the basicerite is spined above as figured for S. minus 
antillensis. Did not the rostra of these several specimens s0 
closely resemble the figures whose labels they bear, I would be 
inclined to think that they had become interchanged. 
Having such a well developed spine at the upper angle of the 
basicerite, Coutiére’s specimens are S. saulcyit (Guérin) more 
certainly than. he suspected at the time (op. cit., p. 52).
