Addendum 



Since the preceding was put in type, new finds of importance have 

 been made in northern China. Not much definite is known as yet 

 about these discoveries ; what has been reported is briefly as follows. 



THE SINANTHROPUS 



The name of Sinanthropus pekincnsis was given in 1927 by David- 

 son Black, Professor of Anatomy at the Peking Union Medical Col- 

 lege, to some ancient human remains that had been found during 

 the period 1920 to 1927 in evidently Pleistocene deposits at Chou 

 Kou Tien, 25 miles from Peking. The amount of material already 

 discovered is relatively large. It consists of a portion of an adult 

 skull and the symphyseal part of a child's lower jaw; many teeth; 

 parts of the calvarium of a juvenile individual; and a nearly com- 

 plete adult calvarium. Recent cable advices have claimed also nine 

 headless skeletons, but of these there is no confirmation. The human 

 remains have thus far been found in five separate loci ; for the most 

 part the remains are embedded in hard travertine ; and they are asso- 

 ciated with mammalian fossil fauna that is believed to be lower 

 Quaternary. 



Professor Black has given a description of three of the teeth 

 and of the fragments of the two mandibles. The adult jaw resembles 

 much the "g" Krapina (Hrdlicka), but is somewhat smaller, less 

 heavy, and the M3 shows a distinct diminution in size as compared 

 to the first and second, which are al>out equal. The latest cable 

 reports on the skull (December 29, 1929) are that it is of a very 

 interesting character. Before the discovery of the adult skull. Sir 

 Arthur Keith, and shortly after that Professor Elliot Smith, ])ub- 

 lished each an account of the finds, with some rather premature 

 though interesting speculations as to its significance. Little definite is 

 known as yet about the site, but a report upon it by Teilhard de 

 Chardin is in preparation. 



A letter to the writer from Professor Black, dated December 13, 

 1929 (received January 16, 1930), reads as follows: 



This is just a hasty chit to let you know that on December 2 ATr. W. C. Pel, 

 who has been in charge of the field-work this year, discovered an uncrushed 

 and almost complete adult Sinanthropus skull in the Chou Kou Tien deposit. 

 The news will be specially announced at a meeting of the Geological Society of 

 China on December 28, but I am sending this off beforehand.
