The genus Anniella was created by Gray * in 18rj2. It was based on 

 a specimen collected by J. O. Goodridge, Surgeon R. X., iii California, 

 and placed among tbe SciucidiV, section Siaphosiuje, near Soridia 

 nneata, Gray ( Lygosonia prcvjjeditum, Boulenger). The species was called 

 Anniella pulchra, Gray. 



In 1864 Prof. E. D. Copet established a special family for this genus 

 under the name of Auniellidiie, which, together with the Anelytropi- 

 die and Acontiidai, was placed in the tribe Tyi)hlophthalmi. 



The characters given were the following: t 



TYPHLOPHTHALMI. 



Temporal bone [squamosal] superior plate .elongate. 



Arches lucomplete or wautiug. 



Articular aud augular couHueut. Suspeusoria one or two. 



Deutary, inferior process elongate. 



Premaxillary siugle or double. 



Clavicles very slender, transverse rudimentary or wanting. 



Mesosternum and other sternal pieces wanting. 



Tongue squamous or iiapillose, simple. — Anelytropid.e, Acontiid.e, Aniellid.^. 



The families of the tribe Typhlophthalmi were thus characterized : 



a Two suspensoria; nostril in the rostral shield. Tongue squamous. 

 Eye concealed by epidermis; occipital segment loosely attached. No frontal under- 

 arch AnELYTKOPIDjE 



Eye distinct; occipital closely articulated; two premaxillaries Acontiid.e
