Cal. Mus. Cum. [Affiliated to the Californian species on supposi- 
titious evidence, and probably distinct. These appear to be from the 
tropical fauna.] Analogue of the W. Indian 7. deeussatus, Gmel.

In P.Z.S8.1861, pp. 229-233, is given a “Catalogue of a Collection of Terres- 
trial and Fluviatile Molluscs, made by O. Salvin, Esq., M.A., in Guatemala: 
by the Rey. H. B. Tristram.” t few of the 49 species occur in Mexican 
collections; none are identical with W. Indian species, except such as 
are of universal occurrence in tropical America; and the 16 new species 
show close generic affinities with the shells of the northern regions of 8. 
America. The shells have been identified from the Cumingian cellection. 
The new species are described, and some of them figured.

* The present posture of binomial nomenclature is well illustrated in this most elabo- 
vate paper, which few naturalists have professed to understand. The shell of which the 
operculum-spine is figured in plate 25. f. 16, is quoted as “ Siphoniwm (Stoa) subere- 
natum, vy. spinosa.” "Che shell described in Maz. Cat. p. 307 is quoted as ‘“ Vermetus 
(Thylacodus) contortus, var. y. contortula (Thylacodus), forma 1, Thylocodus (?) con- 
tortus, var. indentata, Cpr.’ Perhaps the sentences of Kleim and the early writers are 
more easy to understand and remember. The Chitonide of Middendorff (v. First Report, 
p- 214) are simple in comparison.
