Geck()iui:lla, gen. )iov. 



Bohj long-oval, being much longer than wide, instead of 

 vider than long as is the case in the genus Pterijgosoma. 

 Scutum absent. Numerous short plumose liairs are present 

 on the dorsum and sides. Venter only furnished M'ith yery 

 few hairs. Free portion of per'itrenie ratiier long and 

 directed forwards. Coxje not nearly so much fused to- 

 gether as is the rase of Geckubia and PteryyosouiUj and only 

 iurnished with fine liairs. 



This new genus is founded for Geclahia texana. Banks ; 

 as will be seen from the details given above, it is more 

 closely allied to Pterygosonia than to Gickofna, hut differs 

 from the former in the slia| e of the body, which is longer 

 than wide, instead of the reverse, and in the structure of the 

 coxie, which arc only slightly fused with one another.

Geckvbia cletandi, sp. n. 



?. — Body about as wide as long. Dorsal scutum well 

 developed and much wider than long ; it reaches its greatest 

 •\\ idth just before the posterior mai'gin, being angular and 

 salient at this point. The scutum is furnislud with ten 

 liairs, arranged in two transverse rows, an anterior row 

 composed of four hairs (two being placed close together 

 on each side) and a posterior row of six (three on each 

 side of the scutum) ; these hairs are similar in structure 

 to those on the rest of the dorsal surface, and are fairly
