Pterygosoma neumanni, BeH. 



Hab. Specimens from Ayama coloncrum, Gooli I\Iouiitains, 

 Somalilaud. 



It is probatjle that this mite is only a variety of P. agamce, 

 Peters. 



Geckobiella, gen. nov. 



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

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

 Scutum absent. Numerous short plumose hairs are present 

 on the dorsum and sides. Venter only furnished witli very 

 few hairs. Free portion of peritreme rather long and 

 directed forwards. Coxse not nearly so much fused to- 

 getiier as is the case of Geckohia and Pterygosoma, and onJy 

 furnished with fine hairs. 



This new genus is founded for Geckohia texana., Banks ; 

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

 closely allied to Pterygosoma than to Geckohia, but differs 

 from the former in the shape of the body, which is longer 

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

 coxse, which are only slightly fused with one another. 



Geckobiella tcvana^ Banks. 



Hab. Duval County, Texas ; two adult specimens and 

 numerous larvse found on Sceioporus spinosus, var. clarkti

Hab. We have specimens of this mite from Castelfusano, 

 Ostia, and also from Lisbon and Seville. Ihese examples 

 were taken irom between the toes of Tarentola inauritunica. 



Geckvbia clelandi, sp. n. 



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

 develoi)ed and much wider than long ; it reaches its greatest 

 width just before the posterior margin, being angular and 

 salient at this point. The scutum is furnished with ten 

 hairs, arranged in two transverse rows, an anterior row 

 composed of four hairs (two being placed close together 

 on each side) and a posteri(n' 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
