398 On Dr. D. G. Elliot's ' Revieio of the Primates.' 



frequently noted in the literature, while tliere are specimens 

 from Perlis in the British ]Museum. Dr. Elliot, however, 

 has, without comment, transferred Flower's notes on the 

 habits of H. agilis to H. lar, i\\o\\g\\ih^i author was perfectly- 

 correct in assigning the Larut Hills gibbon to H. agilis. 



Under Syinphniangus syndactrjlus the remark on p. 178 

 (Vol. III.) that if the S. s. continentis, Thomas, eventually 

 proves to be a distinct race of the Sumatran species, then it 

 is not at all probable that this species is to be found any- 

 where on the " Malay Peninsula,^' savours of the obvious, 

 and argues a very pre-Darwinian definition of the value of a 

 " species '' on the part of Dr. Elliot. 



Under Symphalangus syndactylus continentis the reference 

 to the type description is misquoted, and should read as 

 p. 301, not p. 30. 



The type locality is Semangko Pass, Selangor-Pahang 

 Boundary, not Gemangko Pass, Selangore, Padang Boundary 

 — '' Padang " being in Sumatra. 



The measurements given are hopelessly mixed. The total 

 length of the skin should be 546, not 846 mm.; while the 

 greatest length of the skull is 127-5, not 43*9. The inter- 

 temporal breadth 43*5, not 107-5 ; and the zygomatic width 

 89, not 86-6. 



The acquisition of additional material shows that the race, 

 though, of course, not a strongly marked one, is sufficiently 

 differentiated from the Sumatran animal. 



In conclusion, we may remark that the paper and typo- 

 graphy of the work are excellent ; while the illustrations, 

 especially those of the skulls, are all that can be desired. 



It is unfortunate, however, that thei*e are an extraordinarily 

 large number of references miscited, and, so far as we have 

 checked them, the measurements are hopelessly incorrect, 

 while the spelling of geographical names is careless and 

 not in accordance with custom or any consistent scheme. 

 Taking one page at random (p. 22, Vol. III.), we find the 

 following errors : — 



line 6, Kcka is the native name of the species, not a place. 



line 7, Sclangorc is now invariably spelt Sclangor. 



line 11, Turutau should redd Tcrutau. 



line 12, Batsu should read Batu, and Bitaug should read 

 Bintang. 



line 14, Langhat should read Tjangkat. 



line 15, Padang should be Padang a«f/Indrapore, Indrapura. 



line 17, Katiman should rend Katcman. 



line 21, Pagce should be Pagi, and Mctawec for the well- 

 known Mentawei has the merit of novelty and 

 nothing else.
