ON TIIE BATRACHIA AND REPTILIA OF COSTA RICA. 115 



REPTILIA LACERTILIA. 

 LEPTOGLOSSA* 



37. Mocoa assata, Cope, Proceed. Acad. Phila. 1864, p. 179. 



From Old Harbor; originally described from the west coast of Salvador. 



38. Mabuia alliacea, sp. nov. 



Distinguished by its long acute muzzle, and reduced number of rows of scales. 

 The former exceeds the width of the head between the eyebrows, and is narrow at 

 the end. There are seven superior labial scuta, of which the fifth subtends the 

 orbit, and is very elongate. The internasals are very narrow and are separated 

 above by a small median scutum in front of the internasal. This scale may be 

 abnormally distinct. Interfrontonasal wider than long, in contact with frontal ; latter 

 long, narrowed behind, its apex received into a notch between the frontoparietals. 



* Epaphelus sumichrastii, Cope, gen. et sp. nov. 



Char. Gen. — A scincoid allied to Gymnophthalmus, without eyelids. Toes 4-5. Nostril in a 

 single plate ; no supranasals ; one loral. Frontonasals distinct. One large supraocular, and one 

 large supraorbital ; frontoparietals and interparietal confluent ; parietals distinct. Scales large, 

 smooth, and subequal. Meatus auditorius open. 



This genus is characterized by the greater simplicity of the cephalic scuta than any of the 

 genera of this group with toes 4-5. 



Char. Specif. — Twelve rows of scales on the body. Labial scuta f , the last inferior very 

 narrow. Behind the symphyseal is a very large mental, which is a little wider than long, and 

 behind it two pairs of large transverse infralabials meet on the middle line. The frontal is very 

 small, scarcely one-fourth the size of the supraorbital, which is a little larger than the interfronto- 

 nasal, and much less than the interparietal. Behind each parietal are two transverse scales, each 

 pair separated on the median line by a scale like those of the back. Three scales margin the vent, 

 of which the median is the least. The extremities appressed to the sides fail to meet by the 

 length of the hand. 



Color light rose-color, metallic on the upper surfaces, the tail bright pink, the top of the head 



bluish. Sides of head and body to groin deep brown, the color abruptly defined above ; below 



unspotted.

Since the above description was written I have obtained a specimen of identical proportions, 



but of twice the size. It was obtained by Dr. Francis Sumichrast in the western part of the State 



of Tehuantepec, and is of interest as the first naked-eyed seine discovered in Mexico. It is 



dedicated to its discoverer, who has added so largely to our knowledge of that country.
