Cope.l ^ * ^ [Nov. 20, 



by him from Panama. On these occasions I defined six species not previ- 

 ously known to science. On the present occasion I am able to determine 

 the contents of a new collection obtained by Dr. Brausford in Nicaragua. 

 This embraces thirty species, of which ten are new to science. The col- 

 lection adds very much to our knowledge of the range of various species, 

 both as to their southward and northward extension. The specimens are 

 the property of the National Museum at Washington, which institution 

 placed them in my hands for identification and description. 



BATRACHIA. 

 Anura. 



1. Bufo haematittcus Cope, Nos. 14178, 14181. Abundant. 



2. Bufo marinus L., Nos. 14198, 14213. One specimen.

 4 Dendrobates tinctorius Ichn., No. 14183. Abundant. 



5. Dendrobates typographus Keferst. No. 14189. Abundant. 



6. Engystoma pictiventre, sp. nov. 



One small metatarsal tubercle. Muzzle anterior to eye equal to twiee 

 long diameter of latter, and projecting well beyond the mouth. Nostrils 

 lateral-terminal. No fold across occiput. Skin everywhere smooth. 

 First finger shorter than second, which reaches end of muzzle when the 

 limb is extended. When the hind limb is extended forwards, the distal 

 end of the astragalus reaches the extremity of the muzzle. First toe very 

 short ; second a good deal longer than fifth ; fourth elongate. 



Color above olivaceous brown. A black band with a very narrow pale 

 superior border extends from the end of the muzzle to the lower part of 

 the groin, the superior border descending posteriorly. No inguinal spot. 

 Below black, with white spots. Those on the abdomen are very large ; 

 those on the femora and tibia are smaller, and those on the thorax and 

 gular region are still smaller. 



Total length of head and body, 22.5 mm. ; of posterior leg, commenc- 

 ing at groin, 29 mm. ; length of posterior foot, 14 mm., of which the 

 astragalar portion measures 4.5 mm. 



No. 14196 ; National Museum. 



7. Hypsiboas miliarius, sp. nov. 



A species above medium size, in which the pollex is free from the index 

 for most of its length, and terminates in a flattened cone, instead of a 

 curved, acute spine. 



Vomerine teeth in two transverse series behind the posterior borders of 

 the choanie, and within the lines of their internal borders. Ostea phar- 

 yngea half the size of the cb.oan.ae. Tongue subround, feebly emarginate 

 posteriorly. Eyes large and prominent. Head Hal and depressed, wider 

 than long, muzzle broadly rounded and with perpendicular profile ; and 

 as long as the orbit's diameter. Canthus rostralis almost wanting, very
