Conus sulcatus Hwass var. philippinensis var. nov. Plate II, fig. 1, 



Tryon, Man. Conchol. 6, PI. 23, figs. 79a-81; 



K. Martin, Foss. v. Java, 1, n. s., PI. I, figs. 11 and 12. 



This is a very fresh looking and well preserved shell, 5 centi- 

 meters high and 2.5 centimeters wide. It is very closely related to 

 both C. sulcatus Hwass, still living in Philippine waters, and to 

 the variety sonde described by Martin from Java. The form fig- 

 ured here has only 1 fine thread-like ridge in the main sulcations 

 instead of 2 or more as in the other varieties. This difference 

 seems scarcely important enough to warrant even a varietal 

 name, but one is given to show that there is a slight difference. 



Locality: Punta Colorada, Aroroy, Masbate, No. 907. 20 



Formation: Pliocene (?) marl. 



Conus odengensis K. Mart. Plate III, fig. 2. 



K. Martin, Foss. v. Java, 1, n. s., PL III, figs. 39-44. 



The specimen figured here is a cast, and all casts are open 

 to doubt, but it agrees with the form C. odengensis more nearly 

 than with anything else it has been compared with. 



Locality: Mount Mangilao, near Davao, Cebu, No. 272. 



Formation: Miocene or Pliocene limestone. 



Elevation : About 200 meters. 



A form not greatly unlike this is C. imperialis Reeve living 

 in waters near Bohol, specimen in Quadras collection, Bureau 

 of Science, Manila. 



Conus djarianensis K. Mart. Plate III, fig. 3. 

 K. Martin, Foss. v. Java, PL III, figs. 45-50. 



This seems to be identical with Martin's species. It also 

 resembles more or less closely C. achetinus Chem. and C. arenatus 

 Brug., the latter living in the seas near Marinduque Island. 



Locality : Raised beach, Bongao, Sulu Archipelago, No. 970. 



Formation: Recent limestone. 



Elevation: 5 meters. 



Conus sp. Plate III, fig. 4. 



This is a small specimen which I did not compare directly 

 with the Javan species, but with a figure merely. I cannot 

 be sure of the determination. It is about the size and shape 



"" These numbers refer to the localities where the fossils were collected ; 

 nearly all of these are shown on the locality map, Plate II.
