prising that at length the half jaw of a quadrumanous anim«I 

 should be brought to light: the circumstance, however, being^ 

 interesting in several respects, we have not deferred its com- 

 munication until further research should put us in possession; 

 of more perfect specimens ; the chances are against the pro- 

 bability of more being brought in for some time — in the in- 

 terval it may be as well at once to add to the Sub-Himalayan 

 list of fossils one species belonging to the order of the Qua- 

 drumana. 



The specimen in question was found in the hills near to the 

 Sutlej, and it appears from the attached matrix to have been 

 derived from a stratum very similar in composition to the one 

 described as occurring at the Maginund deposit. The frag- 

 ment consists of the right half of an upper jaw; the molars as 

 to number are complete; but the first has lost some of its ex- 

 terior enamel : and the fifth has likewise had a portion of the 

 enamel from its hind side chipped off. The second and third 

 molars are a good deal worn, and the state of the fourth and 

 fifth such as to indicate that the animal was perfectly adult. 

 The canine is small, but much mutilated, its insertion into the 

 jaw and its section being all that is distinct. 



From the inspection of the molar teeth, the order to which 

 the animal belonged is sufficiently evident; but there is enough 

 of the orbit remaining to afford additional and very satisfac- 

 tory proof; the lower part of 'the orbit and the start of the 

 zygomatic arch being very distinct, would alone remove all 

 doubt from the subject ; the orbits of the Quadrumana being 

 peculiar and not easily to be confounded with those of other 

 animals. 



On comparison with the delineations of the dentition of this 

 order of animals given by F. Cuvier, the fossil bears some re- 

 semblance to the genus Semnopitkecus; the section of the canine 

 and the form and size of the false molars are very similar to 

 the exemplar taken by F. Cuvier from a head of the species 

 [Semnop.~] Maurtis, a species found in Java: hadthedrawing been 

 taken from the [&] Entellus, a species which inhabits India, the 

 comparison would in this instance have been more satisfactory ; 

 the Maurus being chosen as the type, and no mention made 

 of other difference except length of canines, the various spe- 

 cies may be supposed to present no material departure from 

 the type in form of molars. The third molar in the fossil is so 

 much worn as not to admit of being compared with drawings 

 from unworn teeth ; the fourth is like that of the Maurus, but 

 the fifth does not resemble the analogous molars of any of the 

 existing species as represented by F. Cuvier, for the fossil 

 tooth possesses a small interstitial point of enamel at the inner
