wrong habitats of some of the shells collected by himself, or marked 

 them 'hab.?' in order to mislead the monographers and make as 

 many species as possible. He did not appear to care so much about 

 shells in a scientific point of view as to possess the largest collection 

 in the world. Nothing vexed him so much as having any one doubt 

 the validity of any of his new species, which he selected, generally 

 three of each, from his stock of duplicates. He was also in the habit 

 of changing the author's types whenever he obtained what he sup- 

 posed to be better specimens. No doubt in most cases he was right 

 in replacing the same species. Still, they were not the author's 

 types." 



Under the same date Garrett quotes a letter from Pease, written Apr. 

 21, 1870. "'I shall close up my monograph of Partula as soon as I 

 receive another consignment from Australia, by which I shall receive 

 several species from New Hebrides and Solomon Islands I am desirous 

 of seeing. I make out ninety-four species, of which the localities of 

 eighty are known, viz., fifty -nine Polynesia and twenty-one Papuan. 

 * * * I have divided the several species into typical groups and given 

 their range of distribution and variation. You have credit over your 

 initials for your notes, and sometimes a little more.' " Mr. Garrett 

 adds: "I wrote to a friend in the Sandwich Islands, shortly after 

 Pease's death, to try and get the MSS. They could not be got. I 

 suppose they were sold with his splendid library." 



Oct. 10, 1882: "With regard to Polynesian land shells I have 

 seen nothing to convince me that food has anything to do with the 

 color of the shell. P. rosea and -t'aria, which are the most variable in 

 color, may in some localities be seen in countless numbers on dif- 

 ferent species of shrubs and ferns, old and young of the different 

 colored varieties on the same plant. The same may be said of all the 

 species, ground as well as arboreal." 



Feb. 12, 1883: "Long ago I wrote you in regard to the con- 

 fusion of Pease's duplicates, caused by the hurried packing by persons 

 who knew nothing of the importance of keeping the duplicates separ- 

 ate. * * * Pease himself was very careless, and his children, as he 

 wrote me. amused themselves 'sorting his duplicates,' which were in 

 cigar boxes." 



Nov. 25, 1883 : "I am inclined to believe that many species which 

 are really distinct — especially in the land-shells — gradually merge into 

 each other, just as some genera intergrade."
