BARTSCH: PHILIPPINE LAND MOLLUSKS 17 



Obba moricandi hernandezensis, n. subsp. 



The present race is more elevated and narrower than typical Obba 

 moricandi moricandi Sowerby which comes from Jacna, Bohol. The 

 pronounced characteristic color bands of the spire in the typical form 

 are completely absent and only a faint narrow light-brown thread 

 encircles the base. Our specimens come from Garcia Hernandez, Bohol. 



The type, Cat. No. 21G980, U. S. N. M., measures: altitude, 19.3 

 mm.; greater diameter, 33.2 mm.; lesser diameter, 25.2 mm. 



Obba scrobiculata valenciensis, n. subsp. 



The rought axial sculpture, characteristic of Obba scrobiculata scrobi- 

 culata Pfeiffer, is reduced to a minimum, while the color bands on the 

 upper surface of the typical form are merely indicated by obsolete 

 lines in the present race. The upper surface is marked by broad, 

 light and dark oblique axial zones, which lend it a watered-silk effect. 

 A color band is present on the base. 



The type. Cat. No. 216986', U. S. N. M., comes from Valencia, 

 Bohol, and measures: altitude, 13 mm.; greater diameter, 29.3 mm.; 

 lesser diameter, 23 mm.
