A ivell-hiioiun West Indian species, introduced hy Montagu as 

 taken hy Laskey at Weymouth. Deshayei description of R, pusilla 

 (Anim. s. Vert. vol. viii. p. 479) agrees with it in most particidars. 

 The variety luith ten or twelve, instead of seventeen or eighteen, rihs, 

 alluded to hy Montagu, and referred to by succeeding copyists, is 

 not improbahly a distinct species.
