Subfamily DiplueiNjE. 



This subfamily is distinguished by having three claws, no rastel- 

 lum, and the lip free. The superior mammillae vary from less than 

 one-third the length of the cephalothorax {Hadronyche L. Koch) 

 to more than the whole length (GetJiegiis Thorell). The group 

 Masteriece, though represented in New Guinea and the Pacific 

 Islands, has not been found in Australia or New Zealand. 



The genera resolve themselves into fairly definite groups as 

 follows : — 



1. Six spinnerets HEXATi-iELEiE. 



Four spinnerets only 2. 



2. Tarsal claws with two rows of pectinations. Inferior 



niammill£e near together (not more than 2 diameters 

 apart). Tarsi nnbespined. Scopul« on front two 

 pairs of tarsi and at least partially on same metatarsi. 

 No teeth on the outer margin of the falx-sheath. 

 Sternal sigillse of moderate size and marginal. Front 

 row of eyes procurved. Superior spinnerets generally 



not exceeding half the length of the cephalothorax Beachvthele j;. 



Tarsal claws with one row only of pectinations 3. 



3. Inferior mammillae widely separated, about 4 of their 



diameters apart. No scopulje on any legs. No row of 

 teeth on outer margin of falx-sheath. Sternal sigillse 

 of moderate size and marginal. Superior mammillse at 



least not much shorter than the cephalothorax Macrotiiele^. 



Inferior mammillee close together, about 1 diameter apart. 

 Tarsi of all legs thickly bristled and bespined. Two 

 rows (besides an intermediate at lower end) of teeth 

 on falx-sheath. Sternal sigillse large and removed 

 from margin. Superior mammillse short, hardly exceed- 

 ing two-fifths the length of the cephalothorax Atkace^b. 



Group Beaohythelb^. 



The group into which the genera hereunder collected fall is 

 associated by M. Simon with the genus Biplura under the name 

 of Diplurece, In the first place, however, we have no genera to 

 record following the Diplura side of it. Secondly, as shown by 

 Mr. P. O. Pickard-Cambridge (Proc. Zool. Soc. Lond. 1896,
