364 The Philippine Journal of Science isn 



formed above by three or four small yellow spots; a cream- 

 colored spot on the fifth upper labial ; below canary to yellowish 

 cream with a dark area on the outer edges of each ventral ; latter 

 ventrals mottled and subcaudals almost uniformly dark; occa- 

 sional dark areas on the middle part of the ventrals.

Vanation. — Males and females differ in the number of ven- 

 trals and subcaudals, the average for males being: ventrals, 

 131 ; subcaudals, 28 ; for females : ventrals, 142 ; subcaudals, 22. 

 Four specimens show the postocular fused with the supra-ocular, 

 and No. 197 has a preocular present. There is some variation 

 in the relative length and width of the frontal. Some specimens 

 have them equal and in one or two the length slightly exceeds 

 the width. The females have the underside of the tail uniformly 

 dark, while the males have it mottled and lighter ; Nos. 192, 193, 

 194, and 195 have the second and the third lower labials fused, 

 thus leaving only two labials touching the first chin shields. 



Remarks. — Rather common at altitudes of 800 to 900 meters 

 on the volcano. Specimens were not taken at a higher or a 

 lower altitude. They were found under logs and rotting trash. 

 They feed on earthworms and are in turn preyed upon by 

 Cyclocorus lineatus, which is plentiful in the same locality. The 

 females taken in December contained three undeveloped eggs. 



I take pleasure in dedicating this species to Mr. Homer 

 McNamara, superintendent of the La Carlota Agricultural 

 Station, who rendered able assistance in making collections on the 

 volcano. 



This species represents a distinct section of the genus in having 

 a loreal present. Specimens were usually found in pairs, a male 

 and a female in the same place. (See Table III.) 



Pseudorhabdium oxycephalum Gtinther. 



There is a specimen in the British Museum from Negros. I 

 have not been able to examine specimens of this diminutive snake. 



Hurria rhyncliops Schneider. 



Not uncommon along the coasts. Two specimens in the collec- 

 tion from Hinigaran.
