A. Male*). Lower Herbert River IT^ Nov. 1882 (skin with 

 skull). 



Ps. archeri does not appear to be rare in the rocky scrub at 

 Herbert River. Besides the present individual, wbich was a mature 

 male, Dr. L. obtained one more in the same locality, which in all de- 

 tails agreed with the first, but unfortunately no part of this was 

 preserved. 



From the accounts of this animals resorts, etc., which Dr. L. has 

 published in: Proc. Zool. Soc. Lond. 1884 (p. 407), it appears that 

 Fs. archeri, although a nocturnal animal, is also active during the 

 day. It is preyed upon by Dasyurus maculatus, which is numerous 

 in the same localities, as well as hunted by the natives. It is not 

 shy, but runs, when purSued, very quickly from tree to tree. 

 The name, given it by the natives, is „Tooliah". 

 In Ps. archeri, which by the construction of its toes and tail, 

 (the latter short, haired at the tip, and with a naked under surface), 

 belongs to the true Pseudochiri, the für is unusually soft and close, 

 almost curly, and only smooth and adpressed on the snout, toes 

 and end of the tail. The first third of the tail is very thickly clad 

 with woolly hairs, the apical third with short hairs. The naked line 

 on its lower surface is of moderate length, not equal to half the length 

 of the tail. 



The ears are rather short, but slightly visible beyond the thick hair 

 covering of the head; on their margins the hairs are short, and their 

 inner surface is almost naked. 



Some measurements, taken from the mounted specimen, are here given : 

 Length of the body (head included) . . . about 350 mm 



Length of tail „ 330 „ 2) 



Length of ear (measured along the inner margin) 18 „ 



The nearest ally of Ps. archeri is probably Ps. alhertisii, de- 



scribed by Peteks and Doriä in 1874 (in : Ann. Mus. Civ. Stör. Nat. 



Genova, vol. VI), from Hatam in New Guinea. Besides the dilference 



in colouring between the two species, there appear also to be marked 



1) In the diagnosis in: Proc. Zool. Soc. Lond. 1884, p. 382, by a 

 Printers error $ is placed instead of $ at the figure of the skull. 



2) In the diagnosis in: Proc. Zool. Soc. Lond. 1884, p. 381, the 

 measurements of this and the following species were made from the dried 

 skins, and therefore the estimate was probably too small.
