SMITH : CATALOGUE OF GENUS PARTULA. 429 
4107. ‘* Partula faba Martyn, var. marginata, Tahaa, Coll. Gar- 
rett.’? Eleven adult and three embryonic examples. The form is 
somewhat ventricose ; color dark castaneous with a narrow pale band 
at the suture. One specimen is much smaller than the others and less 
ventricose. This is P. marginata Garr. MS. The variety is included 
among the synonyms of P. faéa in all Dr. Hartman’s catalogues. See 
No. 4100. 
4108. ‘* Partula 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 synonym of P. vtfata Pse. In his MS. work he says, 
after his description of P. vittata: ‘‘ P. microstoma Pse. MS. Coll. 
Pse., which has been referred to vz¢tata, is probably P. faéa weather- 
beaten.’’ Mr. Garrett, to whom Dr. Hartman had sent specimens of 
the shell, wrote (Jan. 25, 1885): ‘‘ Your mzcrostoma is not typical. 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.’’

Nore.—In Dr. Hartman’s MS. and in Proc. Acad. Nat. Sc. Phila., 
1885, p. 206, he indicates that two other synonyms of P. faba are 
represented by specimens in his cabinet, viz., P. dzangulata Pse. MS. 
and P. propingua Pse. Ms. No shells so labeled have been found in 
the collection. Perhaps they are included under Nos. 4094— 
oor 
4109. ‘‘Partula fusca Pse. (Coll. Pse., typical), Raiatea.’’ On 
the back of the card is written: ‘*’The two lower rows of examples 
on this card are probably hybrids between fwsca and fada.’’ 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 
P. fusca or its synonyms. All are dark chestnut-colored, generally 
with a broad, indistinct paler band at the periphery ; in three or four 
the band is not obvious. 
Mr. Garrett wrote (Jan. 25, 1885): ‘‘P. protea, fusca and navt- 
gatoria are the most difficult species to study of any inhabiting Raiatea. 
They are all connected with each other by hybrids, and all are truly 
protean forms.’’
