elliptical or slightly ameboid ; at times trigonal or subquadrate ; largest 

 ones medial ; the dimples anterior to SB are about one-fourth length 

 of those between PLs. AL setae at anterolateral angles of scutum; 

 fairly thin and sparsely plumed ; branches inapparent. Submarginally 

 inserted PL setae about one and a half times as long as ALs; other- 

 wise similar. The four pairs of dorsal setae usurped by scutum all 

 fairly near midline ; anteriormost pair inserted about one-third of 

 distance from anterior margin; fourth pair midway between third 

 pair and posterior margin of scutum. Usurped setae morphologically 

 resembling ALs. Sensillary bases surrounded by a small area free of 

 punctae or pits; closer to AL than PL, the SB-AL distance about 

 one-half that of SB-PL. With a lightly sclerotized ridge anterior to

SB. Sensillae absent in specimens extant. Body setae: Dorsal setae 

 resembling scutal setae ; about 30 to 32 in number (excluding those on 

 scutum); arranged 2.4(2).4(2).(2).6(2), the rest irregular. With 

 about 48 to 50 ventral setae, of which about 22 are postanals. True 

 ventrals very thin and small, about 15 microns in length; pinnae inap- 

 parent. Legs: Sensory setae, sternal setae and coxae I and II as in 

 G. exilis, new species. Coxa III resembling G. evansi, new species, 

 but caudolateral lobe not as well developed ; in ratio 60 (length) : 46 = 

 1.30. Empodium or middle claw of tarsus exceptionally thin and 

 setaceous ; usually missing. 



Type material. — Holotype (C.O.M.R.U. No. 25369) and one para- 

 type ex Rattus bozversi Anderson, Malaya, Selangor, Ulu Langat 

 Forest Reserve, March 4, 1952 (J, R. Audy, for Colonial Office 

 Medical Research Unit). One paratype, ibid., but ex Rattus sabanus 

 (Thomas), August 12. Holotype (U.S.N.M. No. 2165) deposited in 

 U. S. National Museum. One paratype in collection of Colonial Office 

 Medical Research Unit, Kuala Lumpur, and one in that of senior 

 author.
