PHILIPPINE LAND MOLLUSKS 337 



by Dr. C. F. Baker, also has 7 whorls, and measures: Height, 

 87.7 mm; greater diameter, 58.4 mm, while a third. U.S.N.M. No. 

 255864, from the same place, collected by myself, has 6.5 whorls, and 

 measures : Height, 87.5 mm ; greater diameter, 56.9 mm. 



Remarks. — The huge size alone at once distinguishes this race 

 from all the others. 



COCHLOSTTLA RUFOGASTER, subspecies? 



A number of immature specimens from localities not embraced 

 specifically in the races here treated indicate by their distinct fea- 

 tures that they require subspecific recognition, but this will have to 

 await the arrival of more complete material than that at hand. Very 

 distinct from the races treated seem to be some specimens from Pam- 

 panga Province, Sibul Springs, Bulacan Province, and Mount Polio, 

 Banaue, Nueva Vizcaya, a locality unknown to me. 



Then, too, the references of the early writers to Cochlostyla rufo- 

 gaster from localities distant from those from which our material 

 has come indicate further collecting and research in these places. 



For example, Semper in 1874 in his Reisen im Archipel der Phil- 

 ippinen, reports the species from Baler, which is on the east coast 

 in the northeast corner of Tayabas Province, Luzon, a long dis- 

 tance from any of the races that I recognize. This will undoubtedly 

 prove distinct. 



Hidalgo, in his Obras Malacologicas in 1891, reports in addition to 

 many of the recognized races, specimens of Cochlostyla rufogaster 

 from Dingalan, Tayabas; La Union (Camarines Sur ?), Pangas- 

 inan; Tarlac; Zambales; Morong, Rizal Province and Batangas, 

 from none of which I have seen material. Those cited by him from 

 northern Luzon under this name belong to a distinct species. 



Von Mollendorff repeats citing the above in the Abhandlungen der 

 naturforschenden Gesellschaft zu Gorlitz in 1898, under the species. 



It is to be hoped that these notes will call attention to the need of 

 adequate material from the places mentioned, the securing of which 

 will give us a better understanding of the range of the species and its 

 races. 



OBBA MARMORATA AND ITS RACES 



A recent sending of a collection of land shells to the National 

 Museum by the Philippine Bureau of Science for identification and 

 report made it necessary to subject Obha marmorata to a critical 

 review, with the result that some shifting of older names as usually 

 conceived became necessary, and a number of new zoogeographic 

 races required defining.
