Barbour — Three New Neotropical Salientia. 113 



between the eyes and a light spot near the middle of the back. Along the 

 lip on each side there is a broad brilliant silvery white streak extending from 

 the tip of the snout to the fore limb and passing under the tympanum but 

 not extending to the upper lip margin along which there is a dark iron-grey 

 streak which borders the silvery zone below. 



It seems worth while to recognize the genus Syrrhopus for convenience, if 

 for no other reason. The status of the two species which inhabit the United 

 States is reasonably well known. The status, however, of the various 

 names applied to Mexican forms is in the most dire confusion and races of 

 Phylobates and of Syrrhopus seem to be hopelessly confused. However, 

 this type is so very distinct that in spite of the chaos in which the genus 

 stands, it seems reasonably safe to consider it an unknown and undescribed 

 species. 



Among many interesting increments to our collection from Southern 

 South America, some of the most important being from my valued friend 

 Senor don Carlos Reed, appeared this frog, apparently hitherto unknown. 



Paludicola illotus, sp. nov. 



Type M. C. Z. No. 8314. An adult from the Cordillera west of Mendoza, 

 about 7000 alt., Argentina. Don Carlos Reed collector. 



This species may be readily diagnosed in that it possesses vomerine teeth, 

 has no evident tympanum nor lumbar gland ; and has no tarsal tubercle and 

 while the back is very warty, there are no longitudinal folds. 



Description. — Tongue rounded, entire; vomerine teeth in two well devel- 

 oped series, between the choanae, converging very slightly backward, the 

 distance between the series being very slightly greater than the distance of 

 each series from its neighboring choana; nostril nearer tip of snout than 

 eye, its distance from the orbit being slightly less than the eye's diameter; 

 upper eyelid about the width of the interorbital space; no tympanum, a 

 heavy fold over the tympanic area ; fingers rather long, first and second sub- 

 equal; toes without trace of web; the hind limb being extended along the 

 body, the heel reaches the eye; the hind limb being placed vertically to the 

 axis of the body the heels are not quite in contact; there is a very slight 

 trace of web between the toes; the skin of the back is covered with many 

 rather rounded warty tubercles of varying sizes ; the belly is smooth with a 

 discoidal fold moderately indicated. The lower surfaces of the thighs are 

 coarsely granular and all the ventral surfaces of back and limbs present 

 irregularly scattered tubercles appearing very natural at first sight. They 

 are, however, beyond doubt pathological and are probably caused by sub- 

 dermal colonies of protozoan (?gregarine) parasites. 



The color above is dull plumbeous with faint traces of a darker marbling 

 and very faint dark cross bars on the limbs. Below the color is uniform 

 plumbeous throughout, a little lighter than the back. 



Dimensions. — Tip of snout to vent 46 mm. 

 Width of head 18 mm. 



Diameter of eye 5 mm. 



Fore leg from axilla 34 mm. 

 Hind leg from vent 75 mm.
