As would be expected, the bulk of these species (203 out of 367) are the 
same as have been already enumerated in the Reigen Catalogue. Of those 
which do not appear in the Mazatlan lists, no fewer than 37 appear in the 
Panama collections (beside 10 others, known to inhabit the equatorial region). 
Of those not quoted from Mazatlan, 34 are also found in the Acapulco 
region, and 30 at La Paz. Of the whole number, 79 have also been found 
in South America, and 28 in the Galapagos. 38 have also been found in 
Margarita Bay, of which Pyrazus incisus and Siphonaria equilirata are Lower 
Californian rather than Gulf species; but only 13 belong to that portion of 
the Lower Californian fauna which is known to reach 8. Diego, exclusive of 
the same number of Gulf species, which also stray into the 8. Diegan district. 
There are also 10 species, which (with more or less distinctness) represent _ 
West Indian forms. Of these, five, viz. Heterodonax bimaculatus, Erato 
Maugerie, Volvarina varia, Persicula imbricata and phrygia, are new to the 
Gulf fauna: the other five appear in the Reigen Catalogue. 
106. The most extensive collections in the Vancouver district, both as far 
as the number of species and of specimens is concerned, have been made for 
the Smithsonian Institution by Mr. J. G. Swan, teacher at the Indian Reserve, 
Neeah Bay, W.T. For several years * valuable consignments have been 
received from him of shells collected at Cape Flattery, Port Townsend, and 
other stations. Latterly he has trained the native children to pick up shore- 
‘shells in large quantities. The labour of sorting and arranging these has 
been enormous; it has, however, been repaid not only by observing the 
* In consequence of boxes having been received at different times, through the accidents 
of transit, it has not always been possible to ascertain with certainty to whom, among 
simultaneous collectors, should be allowed priority in the discoyery of new species. ;
