3. Cognate words in all languages are reduced 

 to the same form, differentiation being 

 gained where necessary by adding the place 

 of publication. 



4. The place of imprint is omitted (if not a part 

 of the title) except when needed to distin- 

 guish periodicals with the same title, or when 

 the abbreviated form leaves the language of 

 the title in doubt. 



5. In Germanic and Scandinavian languages 

 compound words are abbreviated as though 

 the different parts were distinct. With 

 nouns no period or hyphen is used between 

 the parts, which open with a capital letter. 

 (For example, Entwicklungsmechanik be- 

 comes EntwMech). The parts of compound 

 adjectives are separated by period and a 

 hyphen. 



6. Abbreviations are followed by a period but 

 true contractions are not. Though a useful 

 distinction, this runs counter to habit and is 

 difficult to follow, and seems not to be fol- 

 lowed on occasions by the World list itself. 



7. The following are a few of the more common 

 abbreviations. 



It should be kept in mind that the abbrevia- 

 tions of publications of European scientific 

 bodies refer to the scientific section of the so- 

 ciety. The "Klasse" is given only when the 

 society publishes more than one scientific jour- 

 nal with the same name as is true, for example, 

 of the Vienna Academy of Science. A further 

 point is that the World list follows changes of 



title between 1900-33, as for example, Morph. 

 "Jb. becomes Gegenbaurs Jb. after 1903. How- 

 ever, we have taken the earliest abbreviation to 

 apply retroactively before 1900 despite small 

 changes in title so long as continuity was clearly 

 maintained. 



BRACKET MATERIAL 



Due to the diversity of subject matter, as 

 well as the cost of publication, annotation by 

 abstract or appraisal was considered impossible. 

 However, the information set forth in the square 

 brackets at the end of each reference consti- 

 tutes what may be considered an objective an- 

 notation in compact, codified form. The purpose 

 of the data in these brackets is to give the reader 

 some idea of the character and scope of a pub- 

 lication. The plus signs denote on a three-point 

 scale the degree to which the publication deals 

 with the primates, and is used only when the 

 title does not make this clear or is actually 

 misleading. Thus + + + denotes that the paper 

 is entirely or almost entirely based on the study 

 of primate materials. A single -\- indicates that 

 little attention has been given the primates, 

 while two pluses (++) suggest that the treat- 

 ment of the primates is substantial, roughly 

 equal to that accorded all other forms. The size 

 of the publication must of course be kept in 

 mind. 



Plates, figures, tables and references. The re- 

 mainder of the code up to the colon is designed 

 to afford a rough index of the degree to which 

 the publication is documented, and is to be 

 interpreted as follows: "pV stands for plates 

 which are included in the textual pagination; 

 "f stands for figures, "/" for tables, and "r" 

 for references cited in the bibliography of the 

 article. Figures, tables and references not num- 

 bered in the source are described, for example, 

 by "/", "nt," or "vnt," meaning respectively 

 that the article contains a few tables, that the 

 tables are numerous, or that an exceptionally 

 large number of tables have been used. 



The brackets have also been used to provide 

 a word or phrase descriptive of the character or 

 language of the publication, as for example, 

 "abstract," "review," "lecture," "annotated 

 bibliography of literature." For publications 

 in languages other than the principal ones, or 

 articles difficult of access, especially when they 

 have not been seen in the original, an abstract 

 is sometimes cited. Occasionally publications 

 that are related but do not appear contiguously
