4107. " Partiila faha Martyn, var. inari:;inafij, 'rah:;a, ("oil. Gar- 

 rett." Eleven adult ami three embryonic examples. 'I'he form i.s 

 somewhat ventricose ; i olor dark castaneous with a narrow ])ale band 

 at the suture. One s])ecimen is much smaller than the others and less 

 ventricose. This is /-*. nian^inata (larr. MS. The variety is included 

 among the synonyms q{ F. faba in all Dr. Hartman's catalogues. See 

 No. 4100. 



4108. '^'^ Partttla microstoma Pse. MS. (typical), Raiatea, Coll. 

 Pse. ' ' Twelve specimens, most of them decorticated ; color pale with 

 a broad basal and narrow sutural band reddish brown. In one speci- 

 men, preserving the epidermis, the ground color is dark olivaceous. 

 There is no pillar tooth. In all his earlier catalogues Dr. Hartman 

 makes this a s\non\-m of P. vittata Pse. In his MS. work he says, 

 after his descrijjtion oi F. vittata: " 7\ microstoma Pse. MS. Coll. 

 Pse., -^vhich has been referred to vittata, is probably F. faba weather- 

 beaten." Mr. Garrett, to whom Dr. Hartman had sent specimens of 

 the shell, wrote (Jan. 25, 1885): " Xoxxv microstoma is not ty])ical. It 

 is a large form of radiata. Pease's microstoma was named from the 

 small size of the aperture; your example has a rather large mouth." 

 See other extracts from the Garrett letters under No. 4309, and Hart- 

 man, Proc. Acad. Nat. Sc. Phila., 1885, p. 207. 



Note. — In Dr. Hartman's MS. and in Proc. Acad. Nat. Sc. Phila., 

 1885, J). 206, he indicates that two other synonyms oi F. faba are 

 re])resented by specimens in his cabinet, viz., F. bia/igiilata Pse. MS. 

 and F. propinqita Pse. Ms. No shells so labeled have been found in 

 the collection. Perha])s they are included under Nos. 4094— 

 4097. 



4109. " Partula fusca P.se. (Coll. Pse., typical), Raiatea." On 

 the back of the card is written: "The two lower rows of examples 

 on this card are i)robably hybrids between /"^jv^r and faba.'" Eleven 

 specimens, the two lower rows including seven which are slightly larger 

 than the others, and larger than any others in the collection referred to 

 F. fi/sca or its synonyms. All are dark chestnut-colored, generally 

 with a broad, indistinct paler band at the i)eriphery : in three or four 

 the band is not obvious. 



Mr. Garrett wrote (Jan. 25, 1885); ^^ F. protca, fusca and navi- 

 gatoria are the most difficult species to study of any inhabiting Raiatea. 

 They are all connected with each other by hybrids, and all are tnil} 

 protean forms."
