hairs on the outersidc, tlic np]ici' row standing close to the dorsal bristles. All 

 the tibiae have hairs along the ventral edge. The mid- and hindtibiae have each 

 seven pairs of dorsal bristles. The hindtibia bears on the outerside a great number 

 of hairs arranged in four irregular rows. The longest dorsal apical bristle of the 

 hindtibia is about one-fourth shorter than the first hiudtarsal segment. The 

 apical spines of the hindtarsal segments are stout, the longest of the second segment 

 not reaching to the ape.x of the third. The fourth segment of the hindtarsns is 

 more than twice as long as it is broad. The fifth segment of all the tarsi bears 

 five lateral bri,stles and a subapical hair. This segment has in the ? two short 

 ventral spine-like bristles at the apex. In the <S, however, there are two such 

 bristles on the hindtarsus onl}', the fifth segment of the mid- and foretarsus bearing 

 four. The measurements of the mid- and hindtarsus are as follows : — 



Modified Segments.— The clasper of the c? (PI. XI. fig. 43) is produced into 

 rather a long ])rocess, which bears dorsally one long bristle preceded by two 

 shorter ones. There are, besides, some hairs at the apex and at the ventral edge 

 of the clasper. The finger (f) is long, scythe-shaped, and pointed at the apex, 

 bearing a few hairs, as shown in the figure. • The ninth sternite (PI. XI. fig. 43, ix. st.) 

 is rather broad, and bears several hairs at and near the apex ; it is not divided 

 ventrally. The manubrium (m) is broad at the base, and strongly attenuated 

 towards the end. The s])iral of the penis consists of two coils. The eighth sternite 

 is large, and bears numerous bristles. 



The eighth tergite of the ? bears a few hairs above the stigma, four or five 

 long ones at the apical edge, and a number of small ones besides, as shown in 

 the figure (PI. XI. fig. 44). The stylet is conical. 



Length : <?, 3 mm. ; ? , 4'2 mm. 



We have eight examples of this species, as follows : — 



1 <S, Williams, West Australia, Augnst 1, lOUU, Bettongia penicillata (Mr. 

 B. H. Woodward). 



1 S, Sydney, New South Wales, September 1898, Dasi/wus civerinus. 



3 S6 and 3 ??, Sydney, New South Wales, August 10, 1890, Perawefes 

 nasuta (Dr. J. P. Hill). 



This species is named in honour of Dr. J. P. Hill. 



16. Ceratophyllus woodward! * spec. nov. (PI. X. fig. 41; XI. tig. 42). 



About the same size as C. /till/. 



Head.— The eye is large. There are many fine hairs situated between the 

 antennal groove and the oral edge of the head, and a number of moderately 

 long bristles. Above this hairy area there are two very heavy curved spines 

 on one side of the head and one on the other (PI. X. fig. 41). The bristles on 

 the hinder part of the head are all broken in the specimen, but the grooves 

 indicate their position, as shown in the figure. The dorsum of the head is
