young specimens, but always distinct laterally; body not orange in 

 young. 



Dismission. — This form resembles proterops in belly coloration, lack- 

 ing the large lateral spots of fissidens, but with small, scattered spots 

 or belly unspotted. It resembles fissidens in number of scale rows, 

 labials, and in ventral and caudal counts, but it is very different in 

 dorsal pattern. 



In punctigulans a series of rounded dark spots occurs on each side 

 between the lateral and dorsolateral dark stripes. In young specimens 

 the spots are free, but in older ones they merge medially with a vague 

 dark area. Even in the largest specimens the outer edges of the dark 

 spots are well denned, at least anteriorly, and give a scalloped effect 

 to the inner edge of the dorsolateral light stripe. 



On the tail two light stripes, broader than in fissidens, are separated 

 by a median dark stripe, its outer border well defined. In fissidens 

 the inner edge of the light stripe is well defined only at the anus and 

 on the tail, while in jmnctigularis it is distinct on the posterior part 

 of the body as well. 



Seven supralabials occur on one side in three specimens. Scale rows 

 21 in all. 



The name chitalonensis certainly applies to this subspecies. How- 

 ever, jnmcfigvlwris, proposed 17 years earlier, seems also to refer to 

 the same form. I have not seen the type, but Bailey {op. cit., p. 16) 

 says that "The middorsal band is 5 scales wide anteriorly and 3 wide 

 posteriorly. Anteriorly it is represented by a double row of darker 

 spots, which are evident posteriorly only as scalloped outer bor- 

 ders of the band. This type of coloration is frequent in western 

 Guatemala and Mexico." Accordingly there can be little doubt that 

 this specimen (male, with 125 ventrals) is the same as that here rede- 

 fined. Its locality, however, is rather far removed from the nearest 

 authentic record in Guatemala. Records show that the collector of 

 the specimen, Dr. J. L. LeConte (and J. S. Hawkins), actually was 

 in Honduras, where he was connected for a few months in 1857 with 

 the Honduras Interoceanic Railway Survey. Faunistically the Pa- 

 cific coast mountain ranges of El Salvador are known to be much 

 like those of Guatemala and extreme southeastern Chiapas. It is to 

 this faunal area the present form is confined. Accordingly, if the 

 type of punctigularis actually is from Honduras, it must have been 

 collected on the Pacific side, and in that case very near El Salvador 

 and probably in the same faunal area as is represented by other speci- 

 mens. This would account for the difference between the type of 

 punctigularis and all other Honduras specimens, which are from the 

 Atlantic coast.
