suturis parvis ; mucrone vie monstrante ; intus virescente, rufo 
tincta; marginibus valvarum valde sinuatis, sinu angulato; ad 
jugum vix impressa; limbo valde piloso, setis longis, fortibus, 
incurvatis.

Hab. San Diego ; olim legit T. Nuttall. Mus. suo. 
The sculpture of this species is very strongly marked; the mar- 
ginal hairs rather long, short and crowded *. 
16. PatreLua ?TOREUMA, var. TENUILIRATA. 
P. t. valde depressa, oblonga, diaphana; colore corneo, fusco-pur- 
pureo irregulariter flammato; liris circiter xxii., tenuissimis, inter- 
stitiis obsolete striatis ; apice subprominente, circiter quinta parte 
longitudinis sita; pagina interna valde iridescente. 
Long. 1°38, lat. 1, alt. *28, poll. 
Hab, Monterey ; legit — Hartweg. Mus. Cuming. 
This shell appears to agree with P. toreuma, Rve., in all essential 
respects ; but instead of the fine regular strize of that species, there 
are a few delicate principal ribs, with obsolete strize between. As its 
neighbour, P. Oregona, sometimes developes large ribs, and is at 
other times nearly smooth, this has not been considered a sufficient 
difference to constitute a species, until more is known of its variable 
powers. 
17. GALERUS! SINENSIS, var. FUSCUS. 
G. ? Sinensis, t. rufo-fusca, huc et illuc lineis declivis instructa. 
This shell, marked ‘‘ Gulf of California,” Mus. Cuming, but with- 
out authority, differs essentially from G. mamillaris, Brod. (=regu- 
laris, C. B. Ad.), and is not to be distinguished from the British 
specimens of G. Sinensis, except by the colour, and by a few irre- 
gular diagonal lines here and there, which are probably an individual 
peculiarity. In the collection of R. M‘Andrew, Esq. are several 
specimens of the true G. Sinensis from the Mediterranean, of an 
equally dark colour. It is impossible, therefore, to found a specific 
distinction on this circumstance alone. It is here described in order 
to direct the attention of collectors in that region to the subject. It 
would be very remarkable should the species be proved to inhabit 
so remote a locality. The specimen in question may have been 
imported. 
18. GALERUS SUBREFLEXUS. 
G. t. irregulari, conica, rufo-fusca, radiatim tenui-striata ; striis 
aculeatis ; sutura impressa; vertice involuto, apice depresso ; 
lamina interna apicem versus ad duas trientes reflexa, umbilicum 
magnum monstrante, margine dilatata, haud angulata. 
Lat. *75, alt. *4, poll.

* The specimens described not being my own property, I did not dare to ex- 
amine the insertions of the valves with a view to determine the genus. It is pos- 
sible that some of these species have been already described by Dr. Gould in the 
Expedition Shells (pp. 5, 6), the plates to which are, alas! not yet published.
