4246. " Partula pellucida Pse., Ysabel Isld. , Solomon Islds. (Coll. 

 Cox)." On the back of the card, written with pencil and partly erased, 

 but still legible: " This is the type nitens, compared with the example in 

 the British Museum. Young examples." Over this is written in ink : 

 "This \?, pellucida from Brazier's type examples." Three specimens 

 and two photographs mounted on the same card. The photographs 

 agree well with two of the specimens on the card, but may represent 

 other examples which were returned to Brazier. One of them is 

 the original of the figure published by Dr. Hartman, Proc. Acad. Nat. 

 Sc. Phila., 1886, PI. II, Fig. 17. Dr. Cox sent the specimens to 

 Dr. Hartman, labeled P. coxi Angas MS. P. coxi and pellucida, 

 were collected about the same time by Brazier, and perhaps on the 

 same island. Brazier sent specimens of pellucida to Pease, who 

 described the species in Proc. Z06I. Soc. Lond., 1871, p. 457, but 

 did not figure it. He gave specimens of both species to Dr. Cox, who 

 evidently confounded them, for Angas gave the MS. name coxi 

 to specimens which Dr. Cox had sent him, and the latter sent speci- 

 mens of pellucida to Dr. Hartman labeled coxi. He gave the true 

 coxi, properly labeled, to (Barrett, as appears from Garrett's letter 

 of Jan. 25, 18S5 : "The P. coxi you sent is exactly the same as I 

 received from the Doctor (Cox). The small species you refer to 

 uiicans is jjrobably pellucida Pse. His ' granulated surface ' is only 

 the incremental stria; cutting the spiral lines." The specimens of 

 pellucida were, in fact, referred to micans by E. A. Smith, of the 

 British Museum, when Dr. Hartman sent them to him for comparison 

 in 1879 ; he acknowledged his mistake later (letter of Oct. 2, 1884 ) 

 and Dr. Hartman accepted Garrett's suggestion that the shells were 

 identical with P. pellucida Pse. (see his observations under P. coxi, 

 Proc. Acad. Nat. Sc. Phila., 1886, p. 32). Garrett had s})ecimens of 

 pellucida in his own collection. 



There is ecjual confusion and more uncertainty regarding the habi- 

 tats of the two species. The specimens of both are labeled " Ysabel • 

 Island" in the Hartman collection, but Dr. Hartman gives this 

 locality only for P. coxi in Proc. Acad. Nat. Sc. Phila., 1885, p. 

 217, and in his MS. catalogue; in the same papers /*. pellucida is 

 said to be from Guadalcanar Island. Garrett gives " Guadalcanar
