The presence of this species at Chinajá lends support to the idea that the specimen from the Río de la Pasión listed by Brocchi (1882:116) also is _Bolitoglossa dofleini_. Furthermore, the confirmed presence of this species in the lowlands of El Petén suggests that there may be genetic connection between _B. dofleini_ in the Alta Verapaz and _B. yucatana_ in the Yucatán Peninsula. _Bolitoglossa yucatana_ differs from _B. dofleini_ in having five intercostal spaces between adpressed toes and in having a different color pattern. Both are robust species having no close relationships to other species of _Bolitoglossa_ in northern Central America. The specimen from Chinajá was found in water in the axil of a large elephant-ear plant (_Xanthosoma_) by day in March. Its stomach contained fragments of beetles and a large roach. The natives did not know salamanders and had no name for them. =Bolitoglossa moreleti mulleri= (Brocchi) Chinajá, 2; Río San Román, 1. One specimen is a female having a snout-vent length of 80 mm., a tail length of 82 mm., and a total length of 162 mm. It contains 63 large eggs, the largest of which has a diameter of about three millimeters. This specimen has 13 costal grooves, four intercostal spaces between adpressed toes, and 12-13 vomerine teeth. A juvenile having a snout-vent length of 39 mm. and a tail length of 33 mm. has 12 costal grooves, three intercostal spaces between adpressed toes, and 8-8 vomerine teeth. In life these salamanders were uniformly dull brownish black above with a dull creamy yellow irregular dorsal stripe beginning on the occiput and continuing onto the tail. There are no yellow or orange streaks or flecks on the head or limbs. The specimen from the Río San Román was taken from the stomach of a _Pliocercus euryzonus aequalis_ and has not been studied in detail, because of its poor condition. The present specimens show no tendency for the development of a broad irregular dorsal band that encloses black spots or forms irregular dorsolateral stripes, as is characteristic of _B. moreleti mexicanus_, a subspecies that has been reported from La Libertad (Stuart, 1935:35) and Piedras Negras (Taylor and Smith, 1945:545) in El Petén, and from Xunantunich, British Honduras (Neill and Allen, 1959:20). Schmidt (1936:151) and Stuart (1943:13) found _B. moreleti mulleri_ in bromeliads at Finca Samac, Alta Verapaz. Taylor and Smith's (1945:545) and Neill and Allen's (1959:20) specimens of _B. moreleti mexicanus_ were obtained from bromeliads, but Neill and Allen (_loc. cit._) stated that the natives in British Honduras said that they had found salamanders beneath rubbish on the forest floor. My specimens were obtained from beneath logs on the forest floor in the rainy season. Possibly in drier environments the species characteristically inhabits bromeliads, at least in the dry season. =Bufo marinus= (Linnaeus) Chinajá, 3; 10 km. NNW of Chinajá, 1; 11 km. NNW of Chinajá, 1.
