360 PARTULINA. 



obvious on seeing the superb series of virgulata in Mr. Thaa- 

 num's collection. It is distinct from P. polita by its broad, 

 short spire, sinistral coil, expanded basal lip and white mouth. 

 Four specimens in coll. University of Wisconsin, two in the 

 Cooke collection, one in that of the Academy and several in 

 Mr. Thaanum's collection are essentially alike. It is one of 

 the rarest Molokaian shells. 



PAETULINA TESSELLATA (Newc.). Page 28. Taken abun- 

 dantly in Puunea ("Puanea" of Borcherding's map) at about 

 the western limit of the species; also at the "Pig Wallow " 

 flat above the pipe-line trail, Puulua, Kaunakakai, Cooke and 

 Pilsbry, January, 1913. Eastward it barely reaches the vir- 

 gulata territory. 



PABTULINA RUFA (Newc.). Page 29. Newcomb's type figure 

 is copied photographically in pi. 29, fig. 3. 



PARTULINA PROXIMA (Pease). Page 32. In the redfieldi 

 colony of the heads of Kamalo we found several proximo, pure 

 white except for the purple columella. Thaanum found a 

 small form all with pale green-yellow ground in Kamalo in 

 1906, on the same trees from which he had collected normal 

 (white ground) proxima in 1894. 



We took normal proxima on the east side of Puukolekole, in 

 the P. dwightii colony. Some of Thaanum's series from Ka- 

 wela are very small, length 18.5 mm. 



P. proxima multistrigata Pils., page 34, is evidently, as Mr. 

 Thaanum holds, a western subspecies of proxima, and not of 

 theodorei. It has been collected in some abundance in Kala- 

 maula by Mr. Thaanum. This is probably the original local- 

 ity. P. theodorei has not been found so far west. 



PARTULINA THEODOREI Baldwin, page 33. Another habitat 

 of this apparently valid species is Makakupaia, recorded by 

 Borcherding, from shells collected by Mr. Meyer. This is 

 westward from Baldwin's locality Kawela. Probably all the 

 records from Kawela rest ultimately upon Meyer's authority.

 This species is very closely related to P. redfieldi, but of
