404 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 93 



The whole Mexican population is, however, different from the 

 Central American specimens, in two characters: Ventral counts and 

 pattern of the young and subadults. Young bipunctatus from British 

 Honduras in the Field Museum, recently examined, are not spotted 

 and do not have scalloped inner edges of the lateral stripes as in 

 Mexican specimens; thus their separate identity is certain. The 

 stripes are more distinct in Central American specimens.

Four specimens were secured, all at Piedras Negras, Guatemala 

 (Nos. 109720-2; HMS 7353). The ventral and caudal counts, re- 

 spectively, of these in the order given are : 127, 71 ( 2 ) ; 123, 75 ( $ ) ; 

 128, ? ( $ ) ; 127, 70 ( 9 ). Scale rows 21-21-17; supralabials 8-8; 

 infralabials 10-10; preoculars 1-1; postoculars 2-2 in all. A distinct, 

 regular row of moderately large spots is present on each side of the 

 belly. 



The Museum has two other Mexican specimens, 13 from Teapa, 

 Tabasco (No. 46590), and San Andres Tuxtla, Veracruz (No. 46389). 

 The last is somewhat intermediate between /. fissidens and /. pro- 

 terops.

 1941. 



Ten specimens were secured, from the following localities: Teque- 

 yutepec, Veracruz (Nos. 109769-73) ; Potrero Viejo, Veracruz (Nos. 

 109767-8); Cuautlapan, Veracruz (Nos. 109764-6). The Teque- 

 yutepec specimens were found under stones on grassy slopes of the 

 mountainous area west of Jalapa, after a period of rains in the middle 

 of the dry season. 



The Museum has 10 other specimens (see Smith, loc. cit.). 



CONIOPHANES FISSIDENS PUNCTIGULARIS Cope 



Coniophanes fissidens yunctigularis Smith, Proc. U. S. Nat. Mus., vol. 91, pp. 

 107-109, map fig. 33, 1941. 



Forty-five specimens, all from the vicinity of Escuintla, Chiapas, 

 are in the collections: Finca Juarez (Nos. 109723-5) ; Salto de Agua 

 ( Nos. 109726-7) ; Cruz de Piedra (Nos. 109728-35) : La Esperanza 

 (Nos. 109736-63, HMS Nos. 16556, 17053, 17162, 17279). Some were 

 found during the day in rotten logs, but by far the greater part was 

 found at night along trails through forest or coffee groves. 



The Museum has five other specimens (see Smith, loc. cit.).
