44 JOURNAL OF THE 



guided by those adopted by Anton Ausserer\ and the Rev. 

 O. P. Cambridge', who have given considerable study to 

 members of the Territelarice. 



I have followed the classification adopted by Ausserer in 

 his Beitraege zur Keiintidss dtr l^rritelaricB. 



I subjoin, for clearness, a brief synopsis of his Classifica- 

 tion. 



Suborder Territdarice. This was divided by Thorell into 

 3 families, as follows * 



2, lung sacs Catadisoid(s. 



4, luner sacks, 



a. AYithout spint) erets Liphistoidice' 



b. With spinnerets TheraphosoidcB ^ 



The family Theraphosoidae, Thorell, is further divided into 

 three subfamilies as follows : 



Maxillge well broadened at the base, palpi inserted laterally, . Atypinae Thorell 

 Maxillae little broadened at base, palpi inserted laterally 



Eriodontinse Ausserer. 

 Maxillffi not broadened at base, palpi inserted on the end, 



Theraphosinae Thorell. 



The Theraphosoidae are then further divided into two 

 groups, based on the relative elevation of the caput above 

 the throax. 



a. Caput well elevated, ^picephoM' 



b. Caput not much elevated, Tapinocephali. 



In specific descriptions I have endeavored to not repeat 

 characters which seem at present generic, so that in most 

 cases it will require both the generic and specific characters 

 to identify a single species ; for this reason I have given the 

 characters of the genus Tachylomertcs, established by 

 Ausserer. 



Family THERAPHOSOID^, Thorell. 

 Subfamily Eriodontinae, Auss. 



1. Genus Nidivalvata, n. gen. 

 (nidus, nest, valvata, having folding doors.) 

 (PI. V, figs. 8, 9, 10, 13, 23.) 

 Ceph'x little longer than broad ; greatest breadth at middle*, tapering 

 very gently and equally to both ends ; edges of posterior half slightly 

 scalloped ; small, deep, circular, depression in center from which radiate 

 to edges of ceph'x 6 depressed lines quite well marked. Caput well ele- 

 vated, sloping to thorax gently, not broadly a' died as in Murmekiaphilt. 

 In front, caput gently drawn to a short, blunt point about which the eyes
