true ova/is, two of the banded variety and three of the type. The 

 shells I formerly supposed to be ova/is I now refer to lagufiris. On 

 looking over my journal I see recorded the discovery of a new ground 

 Partula in the Faaloa Valley on the east coast of Raiatea, and I gave 

 it the provisional name casta nca. Mr. Pease, when he l)ought my col- 

 lection, adopted all my provisional names which I gave to each species 

 when discovered. As I did not use the name oralis, I have every rea- 

 son to believe that he renamed the shell. His description accords 

 much better with (my) casfaiica than with the shell I formerly sup- 

 posed to be oralis. It is very closely allied to vittafa, as you will 

 remark from the description." Subsequently both Dr. Hartman and 

 Mr. Garrett regarded castanca Pse. MS. and Garr. MS. as a variety of 

 vittata Pse. (see note under No. 4123). Mr. Garrett appears to have 

 returned to his idea that oralis was a synonym or variety of li/t^iil'ris, 

 and he gives it as such in Journ. Acad. Nat. Sci. Phila. , IX, \). 79. 

 But it does not appear that this was the shell which Dr. Hartman 

 called 07'alis, and it is doubtful if Garrett had that form in his collec- 

 tion. They made direct comparisons of specimens. See extracts from 

 Mr. Garrett's letter under Nos. 4130 and 4125 ; the shell referred to 

 by Garrett, quoted under the latter number, may be the true oralis. 



4129. Partula navigatoria Pfr. ''Partula rariabilis Pse. = iiari- 

 gatoria Pfr., Raiatea, Coll. Pse., Garr. and Geale." Fourteen speci- 

 mens, varying much in size and form ; all are pale brown or cinereous 

 brown, with oblique streaks of a darker color, and without bands. The 

 name uarigatoria is a misnomer, but has remained in use. Mr. Pease 

 seems to have been in doubt as to the identity of this species. He wrote 

 to Mr. Garrett, April 21, 1870 (quoted in Garrett's letter, March 15, 

 1882): "Among the species I have lately determined is ' navigatoria ' 

 (Pfr.) which is a small variety oi faba.'' In Pease's list of Polynesian 

 shells, Proc. Zool. Soc, 1871, Partula navigatoria does not appear. 

 Carpenter referred ///.s^v? Pse. to navigatoria. See No. 41 16. 



Mr. Garrett wrote to Dr. Hartman, Feb. 12, 1883: '■'P. naviga- 

 toria is frequently banded and some forms cannot be distinguished from 

 some elongated forms oifusea. Had the former been a strictly ground 

 species I would have made it synonymous with the latter." See under 

 No. 411 9 and No. 4109. 



4130. " Partula lugubris Pse., Raiatea, Coll. Pse." Six specimens, 

 four immature and much smaller than the others. Five are dark brown, 

 lighter above, with a narrow pale peripheral band ; the other (imma-
