DR. F. A. JENTINK. MAMMALS. 369 



Female with S raammae. Tail with very short stiff, dark colored hairs; three hairs 

 from each scale, the midmost somewhat longer than the other two, which hâve the length of 

 the scale; thèse hairs grow somewhat longer towards the end of the tail. 



This mouse seems to be very common everyvvhere along the coasts of New Guinea, 

 cf. my paper "On the New Guinea Mammals" (Notes Leyden Muséum, vol. XXVIII, 1906, 

 p. 1S1).

a. adult maie, Tami River, 13 May 1903. 



b. young female, Humboldt Bay, 25 March 1903. 



c. adult maie, Tawarin, iS June 1903. 



d. adult female, Wendèsi. 



e. young maie, with skeleton, Merauke. 



/, g. upper jaw, near Sentani Lake, and lower jaw, Tobadi, Humboldt Bay. 



As a rule the measurements recorded as having been taken from thèse animais are not 

 very trustworthy the skins being dried ones or stuffed; therefore I take advantage of the op- 

 portunity of disposing of fresh (alcoholic) spécimens to give some measurements of the adult 

 maie from the Tami River, Humboldt Bay, taken in the fiesh :

The skull of this enormous animal présents the following measurements: 



basai length 97 



greatest breadth 70 ') 



nasals, length 42 



palatal length 57 



length of the four upper molars . 26 



The molars are not at ail used, so that the animal had not yet attained its full size. 

 How extremely variable thèse measurements are, grow évident by comparing the young adult 

 skull from the Tami River-individual with the skull of an adult adult male-specimen from 

 Schouten Islands (Geelvink Bay), in our Muséum, almost albino with very used molars and 

 nearly vanished sutures; greatest breadth 66 mM., nasals, length 34 mm., and the four upper 

 molars 25 mM. (the skull being partly smashed, I cannot record the basai length nor the 

 palatal length). Still smaller dimensions présents the skull of an adult adult female-specimen, 



1) The partly smashed skull of an adult maie, from Hatam, N. G., in our collection, has still stouter dimen- 

 sions, viz. : greatest breadth 74 mM. ; nasals, length 44 mM. ; upper molars 27 mM.
