ANNOTATED CATALOGUE of the SPECIES of COA'US, 

 COLLECTED IN THE SOUTH SEA ISLANDS. 



By ANDREW GARllETT. 



On looking over my notes and Journals made during many 

 years devoted to Conchological researches in the various South 

 Sea Islands, I have selected and tabulated the following list of 

 Cones collected in all parts of Polynesia, hoping it will not be 

 devoid of interest to those engaged in elucidating the difficult 

 problem of the geographical distribution of the mollusca. 



It is worthy of remark that every species mentioned in the 

 present list has been collected by the writer, so that the locations 

 and range of each can be relied on as correct. Of course further 

 research will increase the number of species, and prove that others 

 have a more extended range than given in this Catalogue. 



I have not attempted to elucidate the cause of variation, 

 which, in many cases, is as great in the same group of Islands as 

 in those species common to remote localities. Shells inhabiting 

 Western Polynesia are most generally larger and firmer than 

 Eastern Polynesian examples, but in some instances the contrary 

 takes place. 



In order to acquire a true knowledge of geographical distiibu- 

 tion, local lists carefully tabulated will be of material aid in solving 

 the problem. In future papers I purpose to catalogue other 

 genera in the san-ie manner.
