she in no wise suggested my naming these forms. ^ I have done 

 so because I think more material will prove them to be valid 

 geographic races. 



Enygrus australis (Montrouzier) 



Boa australis Montrouzier, Rev. et Mag. Zool., 12, 1860, p. 95. 

 Enygrus australis Boulenger, Cat. Snakes Brit. Mus., 1, 1893, p. 105. 



Mann procured four at Graciosa Bay, Santa Cruz Islands, and 

 writes me that they were very common there. He also preserved 

 three on Ugi. 



Enygrus carinatus (Schneider) 



Boa carinata Schneider, Hist. Amph., 2, 1801, p. 261. 



Enygrus carinatus Boulenger, Cat. Snakes Brit. Mus., 1, 1893, p. 107. 



Several color phases are represented in Mann's series of one 

 from Bio Island, one from Ysabel, seven from Malaita, and 

 twelve from Ugi. 



Enygrus bibronii Hombr. and Jacq. 



Enygrus bibronii Hombr. and Jacq., Voy. Pole Sud (Astrolabe et Zelee),

1 She writes, under date of May 2, 1921, as follows: " I have at last found time to com- 

 pare your drawings with the types and other specimens of Typhlops olivaceus. Neither 

 drawing corresponds exactly, and as the differences are very difficult to describe, I have made 

 some very rough sketches which may convey my meaning better than words. You will 

 notice that although they all agree in essentials, there is considerable variation, especially 

 in the shape of the rostral. Personally, judging from your drawings alone, I should say that 

 14,269 was T. olivaceus with an extra prominent snout, and that 14,270 resembled T. cumingi 

 in general outline, etc. In none of our specimens are the excrescences as marked as in 

 yours."
