S. candeana Lea, Guppy, of. cit., p. 221. 
Mr. J. H. Ponsonby has presented specimens of this 
species to the British Museum, which he received direct from 
Trinidad. If S. candeana of Lea be synonymous, as stated by

With this species I am inclined to unite P. lanierianus 
@Orbigny, P. tentatus Morelet, and P. Redfield C. B. Adams. 
If this union of species be correct, the range of this species 
becomes extended to Jamaica and the Isle of Pines. 
Mr. Guppy appears to have included two species under 
his P. meniscus, for, in the original description he remarks that
