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 Pijrazus inaisris axA Siphonaria cequilirata are Lower 

 Califomian rather than Gulf species ; but only 13 belong to that portion of 

 the Lower Californian fauna which is known to reach S. Diego, exclusive of 

 the same number of Gulf species, which also stray into the S. Diegan district. 

 There are also 10 species, which (with more or less distinctness) represent 

 "West Indian forms. Of these, five, viz. Ileterodonax himaculatus, Erato 

 Maw/ericB, Volvarina varia, Persioula imbrieata and jphrygia, are new to the 

 Gulf fauna : the other five appear in the Eeigen 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
