of Negros. We may therefore assume the north shore of Negros to be the 

 home of Cochlostyla fulgetrum, fulgetrum Broderip. 



The present sending from Tayasan, which lies on the middle of the 

 east coast of Negros, presents shells which are much more slender, there- 

 fore taller than the typical Cochlostyla fulgetrum fulgetrum,. The ground 

 color, also, is olive green, while in Cochlostyla fulgetrum. fulgetrum it tends 

 to yellow. Occasional specimens of both races have a pale reddish brown 

 ground color. A brown peripheral band may be present or absent in both. 

 It is not surprising that the specimens of the north and east coast should 

 be different for the two regions are separated by high mountains. It is 

 without hesitancy, therefore, that the name Cochlostyla fulgetrum tayasana 

 is now applied to the race from Tayasan, which will probably be found 

 to extend over the eastern portion of Negros Oriental. The type and four 

 specimens form Cat. No. 219,037, U. S. N. M., and were donated by Mr. 

 Webb. 



Cochlostyla nimbosa antiqua, new subspecies. 



Broderip, in describing Bulinus nimbosus in the Proceedings of the 

 Zoological Society of London, 1840, page 121, defines four varieties. Vari- 

 eties a, b and c have the ground color brown, and come from the Island 

 of Negros. The variety d, on the other hand, has a pale yellow ground 

 color and comes from the Island of Panay. In spite of the fact that so 

 many names have been bestowed upon Philippine Cochlostylas, no one 

 appears to have separated these two races, which are quite distinct. Since 

 Reeve has figured the dark colored form from the Island of Negros under 

 the name of Bulimus nimbosus, Conchologia Iconica, plate 4, figure 17, we 

 may consider the name restricted to this form, and I now give the name 

 Cochlostyla ni?nbosa antiqua to the race from the Island of Panay. The 

 type and two specimens received from Mr. Webb are entered: Cat. No. 

 310,072, U. S. N. M. 



The group of Cochlostyla sarcinosa is sadly in need of revision. The 

 name is usually credited to Ferussac, but there while Ferussac used the 

 name sarcinosa in 1822 in his "Tableaux systematiques des Animaux 

 Mollusques," on page 47, number 323, the name as here applied has no 

 status for it is a nomen nudem. In literature one frequently finds the 

 name given as dating from Ferussac-Deshayes " Histoire Naturelle Gen6rale 

 et Particuliere des Mollusques Terrestres et Fluviatiles" on page 267 and 

 figured on plate 169, figures 1 and 7, but unfortunately the plates did not 

 bear any name when they were issued, and the text for the part embracing 

 this species was not published until 1850. In the mean time (1840), Broderip 

 in the Proceedings of the Zoological Society of London, pages 121-123, 

 reported on Cuming's collection from the Philippines, Helix (Cochlostyla) 

 sarcinosa with varieties a-g. Of these varieties, a and b are from the Island 

 of Negros, c is from an unknown source, d is from the Island of Guimaras, 

 e and f are from the Island of Masbate, and g is from an unknown locality. 

 Subsequent authors have looked upon the globular shells from Masbate 

 as the typical form and we may therefore restrict the name Cochlostyla
