COCHLOSTYLA OF MINDORO PROVINCE 501 



I shall therefore consider that the nuclei proclaim two phylogenetic 

 groups, which I shall call species and under which I shall recognize 

 the known races, as subspecies. How constant these races are may- 

 be inferred from plate 115 representing Cochlostyla caniceps caniceps, 

 in which I show a series of specimens taken at random from a collection 

 made at Lake Naujan, to illustrate the constancy of character. 



COCHLOSTYLA (CHRYSALLIS) ASPERSA (Grateloup) 



It is unfortunate that this species cannot carry the name Cochlostyla 

 mindoroensis under which the various races belonging to it are reposing 

 in the existing collections. Grateloup evidently received from Cuming 

 some specimens labeled Bulimus mindoroensis (Broderip) but he did 

 not approve of this name and gave the species the name Bulimus 

 aspersa, defining it, in the Actes de la Societe Linneenne, volume 11, 

 page 164, in 1840, in a very few words and mentioning Manila as its 

 habitat. A little later, in the same year and publication, pages 

 421-422, he redefines it and figures it on plate 4 as figure 3, in an 

 unmistakable manner. He also here places as variety A his Bulimus 

 wagneri, which in the previous paper he had believed to have come from 

 Peru. Broderip 's Bulinus mindoroensis, not being published until the 

 following year, must necessarily, for priority reason, give way to 

 Grateloup 's older name. 



In recognizing a number of zoogeographic races in the island of 

 Mindoro of Cochlostyla aspersa, I am going to retain the name mindo- 

 roensis for one of the races, the one coming from the region of Puerto 

 Galera, which agrees best with Reeve's figure, published on plate 4, 

 figure 15, in the Conchologia Iconica. Reeve, being the first one to 

 figure a representative under this name, may be considered as fixing 

 it to the form in question, since Broderip has given us the wide range 

 of varieties a-k in the definition of his species. 



I am also retaining Grateloup's name wagneri for a somewhat smaller 

 and more elongate race from the region of Lake Naujan, probably 

 from one of the hills on the east coast of the lake. Most of the speci- 

 mens that I am referring to Cochlostyla mindoroensis wagneri in our 

 collection are labeled merely, if labeled at all, Lake Naujan. The 

 largest series was obtained by the Menage Expedition of Worcester 

 and Bourns. I am led to retain wagneri because a large series of 

 specimens collected by Mr. de Mesa at Ariod, some little distance 

 northwest of Lake Naujan, are larger and represent typical Cochlostyla 

 aspersa. Some of the Worcester and Bourns collections labeled 

 Naujan belong to this larger, more globose, and chubby race, although 

 they are also labeled Lake Naujan. This makes me believe that 

 they represent a different habitat from that occupied by Cochlostyla. 

 aspersa wagneri.
