156 The Ohio Naturalist. [Vol. VII, No. 7, 



(6) Dromicus oniiltemanus collected at Gualan, Guatemala, 

 Januaiy 22, 1905. Length, 14^ inches; tail 5^ inches. Ventral 

 scutes 128, sub-caudal scutes, 81 pair. Scales on this spec- 

 imen are in 17 rows, instead of in 19, as given in the Biologia 

 Amer. Cen. by Gunther. Mr. H. H. Smith collected this species 

 in Mexico at an altitude of 8,000 feet. 



SPILOTES. 



Spilotes salvini, collected at Gualan, Guatemala, January 22, 

 1905. Length 88j inches, tail 24^ inches; which is unusually 

 large for this snake. Gunther gives 77 inches as the maximum. 

 Gastrosteges 206, urosteges 129 pairs, and entire. In coloration 

 it has much more black than the description or figure of this 

 species in the Biol. Amer. Central, and a correspondingly less 

 amount of A^ellow. The head plates are regular and correspond 

 to the description very closely. 



DRYMOBIUS. 



Drymobius caeruleus, was collected at Gualan, Guatemala, 

 January 25, 1905. Length, 39^ inches, tail 14^ inches. Ventral 

 scutes 153, sub-caudals, 116 pair. Nine upper labials, 4th, 5th 

 and 6th in the orbit. 



DIPSAS. 



Dipsas splendida, represented by two specimens (No. 33, and 

 No. 12). The small caliber of the neck of this species in com- 

 parison with the size of the head and body make these specimens 

 the most striking ones in the collection. 



No. 12 was collected at Los Amates, Guatemala, February 

 12, 1905. Length, 28j inches, tail 8\ inches, abdominal scutes 

 240, sub-caudal scutes 142 pairs, one ante-orbital; had 37 dark 

 spots on the body, and 24 on the tail. Stomach contained the 

 remains of three small lizards. 



No. 33 was collected at Los Amates, Guatemala, February 

 23, 1905. Length, 334 inches, tail, 104 inches; sub-caudal 

 scutes 147 pair, ventral scutes 231 pair; two ante-orbitals ; the 

 vertebral scales are longer than broad anteriorly, but broader 

 than long posteriorly in both specimens; adult ^ ; neck very 

 slender. This snake contained six unincubated eggs, with a 

 very light covering membrane, the species being in all probability 

 ovo viviparous. The stomach contained the remains of three 

 lizards and two beetles. 



BOTHROPS. 



Bothrops atrox; this sepcies is represented by two spec- 

 imens, the only poisonous snakes in the collection ; one in adult, 

 which looks able to uphold the reputation of its insular relative, 

 the Fer-de-lance ; the other a young specimen.
