[Cope. 



Tlie color is olivaceous, yellowish below. A blue band crosses the pre- 

 orbital bone above, and another follows the premaxillary border and 

 passes along the inferior border of the orbit. Below this, another blue 

 line crosses the cheek. Other blue bands have been obscured by the alco- 

 hol. Flap, plain black. 



Total length, M. .113 ; to end of flap, .033 ; to line of anal fin, .054 ; to 

 base of caudal fin, .091. 



This species much resembles the common L. pallidus Mitch, of the United 

 States. It has, however, about ten less scales in the lateral line, and the 

 gill-rakers are rather short and quite obtuse. It is also allied to, but still 

 more difterent from, the L. humilis. 



This species is the most southern of the group to which it belongs, and, 

 excepting the species of Micropterus, the first known from Mexican waters. 



Batrachia. 

 Rana halecina Kalm. 



Reptilia. 

 Phrynosoma cornutum Harl. 

 The most southern locality for this species. 



HOLBROOKIA TEXANA TrOSCh. 



The most southern locality for this species. 



SCELOPORUS TORQUATUS Wicgm. 



This species is abundant at Monterey, and also at Laredo, on the Rio 

 Grande. 



SCELOPORUS VARIABILIS Wicgm. 



The most northern locality for this species. 



Remarks. 



In this small collection we have a mixture of the nearctic and neotropi- 

 cal faunai. Among the fishes, well-known northern genera swim in the 

 waters of Monterey with the two neotropical types Heros and Tetragonop- 

 terus. Two of the reptilian species are the common forms of Texas, while 

 the Sedoporm variabilis is a species of the Tierra Caliente, which extends 

 as far as Tehuantepec. 



II. Jalapa, Vera Cruz, Flohr. 

 The following species were presented to me by my friend Mr. Flohr, of 

 the city of Mexico. Some of the species are rare or new. 



Eumeces furcirostris, sp. nov. 



The characters of this species may be best understood by the following 

 table of the Mexican and Central American species of this genus : 



I. No nasofrenal plate. 



«. Three supraorbital plates. 



Frontal transversely divided ; twenty-four rows of scales ; a pale-bordered
