the feet, in the long thick black fur (which nearly or quite 

 hides the spines), in the thickly clothed spineless under 

 surface, Aud in the uniform whiteness of the spines. But the 

 size is less, as is shown by the skull-measurements, the brain- 

 case shorter and narrower, and the rostrum proportionately 

 and markedly moro, slender, its breadth at 40 mm. from 

 the tip 10 mm. in the largest specimen, as compared with 

 .13 mm. in the type of bartoni, and 12"8 mm. at 70 mm. from 

 the tip as compared with 15*2 mm. All tiie four available 

 specimens, representing both sexes, agree in the proportions 

 of the skull and tiie peculiar slenderness of the snout. 



Of the following skull-measurements, the first in each case 

 is that of the type of citmuis and the second that of the type of 

 hartoni, and these will show the differences between the two 

 forms : — 



Total length 183, 184 mm.; basal length 171, 174; breadth 

 of brain-case 54, 59'5 ; muzzle from level of lacrymal canal 

 117, 115 ; gnatliion to b:ick of palatal bones 1(J0, l<il ; ante- 

 rior root of zygoma to b ick of palatal bones 41, 40*5; least 

 interorbital breadth 17"5, 20.

[P.S. — In the above account Mr. Oldfield Thomas and I 

 have only dealt with the five-toed Zaylossus hartoni bartoni^ 

 Thos.,and its northern subspecies Z.bartoni cliniius — i. e., the 

 Species of Zaylossus iidiabiting New Guinea east of the Fly 

 liiver. The species found west of the Fly E,iver is the type 

 of the genus Zaglossus, viz., Zaglossus bruijni (Peters and 

 l)oria) . This species exhibits much greater external variation 

 than does Z. barlorn, and I find at least six recognizable 

 forms, four of which have been already named and described. 



In spite of Mr. Glover Allen's very definite assertions, I 

 am convinced, like Dr. Kerbert, that these forms are not 

 individual aberrations, but represent well-defined local sub- 

 species. Of the four described races, we know absolutely 

 the locality of one of them only — Zaglossus bruijni good- 

 felloiviif Thos., — which was descriljcd from specimens 

 captured on the island of Salwatti. Of the other three, we 

 can safely assume the locality' of the typical Z. bruijni bruijni 

 to be the Arfak Peninsula (by the typical race I mean the 

 pale-headed black-brown form described by Gervais, and 

 assigned to bruijni by him, for the actual typo of this form is a
