Propus vermiformis, gen. et sp. nov. 



Char. Gen. Family Ghalcididae. Scales smooth, in anniili ; 

 a lateral longitudinal fold. Limbs one pair, the anterior only, 

 without digits or claws. A few pores at the side of the vent. 

 Head shields above, two internasals, one frontal, a narrow super- 

 ciliary which descends in front of each e3'e, and a pair of parie- 

 tals. Nostrils on the suture between intern asal and first labial; 

 a loreal shield. Tail elongate. 



This genus is near to the Ophiognomon^ discovered by Prof. 

 Orton in Equador, and is principally distinguished from it by the 

 absence of the posterior limbs. 



Char. Sjyecijic. Scales in twenty-six longitudinal rows on the 

 posterior, and twenty rows on the anterior part (with closed 

 lateral folds) of the body, and fifty-one transverse annuli between 

 the nape and the vent. Anteriorly they are imbricate on the 

 dorsal surface ; posteriorly they are truncate. The abdominal and 

 thoracic scales are subequal, those of the seventh row from the 

 gular groove excepted, which embrace two between the fore limbs, 

 and are not longer but wider than the others, but not so wide as 

 long. 



There are five upper labial plates, of which the third and 

 fourth are of subequal length, and bound the orbit below ; .the 

 second is the least. A large rhombic temporal separates the 

 fourth and fifth from the parietals, behind which are two others. 

 There are four narrow inferior labials and three infralabials, of 

 which the two anterior are in contact on the middle line, with 

 those of the opposite side. They are preceded by a large geneial 

 and small symphyseal. The last infralabials are separated from 

 each other by four narrower scuta and from the temporal on each 

 side by two scales. Two pores on each side of the vent, and three 

 elongated scuta in front of it. Tail subquadrate in section (per- 

 haps contracted).
