Remarks.—The only two specimens of Clelia clelia examined from 
the Pacific slopes of Mexico north of the Isthmus of Tehuantepec are 
markedly different from other Mexican specimens in lacking dark 
spots at the tips of the dorsal scales. They are named: 
CLELIA CLELIA IMMACULATA, new subspecies 
Holotype.—U.S.N.M. No. 24966, from “Guadalajara,” Jalisco, col- 
lected by J. J. Major. 
Paratype-—EHT-HMS No. 4568 from Paso del Rio, Colima. 
Diagnosis —Like Clelia clelia, except no dark spots present on tips 
of dorsal scales. 
Description of holotype—Supralabials 7-7; infralabials 8-8; pos- 
terior section of nasal elongate; a small loreal; 1 preocular; 2 post- 
oculars; temporals, 2-8; dorsals 19-19-17 rows; ventrals 206; anal
