closely allied to a species from the Cretaceous of France. Desmoceras 

 is represented by two forms, one of which is considered to be a new 

 variety of the species D. Dawsoni which Dr. Whiteaves described 

 from the Queen Charlotte Islands, whilst the other is regarded as new. 



All the species are well illustrated on the six plates accompanying 

 the work. 



We most heartily congratulate the author upon this further most 

 interesting contribution to our knowledge of the Cretaceous Cephalo- 

 poda from the Hokkaido. G. C. 0. 



III. — Second Eeport of the Geological Survey of Natal and 

 ZuLULAND. By William Anderson, F.E.S.E., F.G.S., Govern- 

 ment Geologist. 4to; pp. 171, with 11 plates and maps. (London, 

 1904 : West, Newman & Co., 54, Hatton Garden.) 



THE Report contains an account of the Survey operations for the 

 years 1901-2, with two valuable and important contributions 

 to the Palaeontology of East Africa, one by Mr. Eobert Etheridge, 

 of Sydney, and the other by Mr. A, C. Seward, F.R.S., of Cambridge. 

 It should be mentioned that Mr. W. Anderson is still the only 

 member of the Survey Staff, and that its oflBces are limited to two 

 small rooms in Pietermaritzburg, altogether inadequate for the proper 

 storage of the rock specimens and fossils ; and but for the fact 

 that various collections were promptly sent for identification to 

 palgeontologists in different parts of the world, their accumulation 

 would have made the offices practically inaccessible ! On the other 

 hand, the Natal Government do not seem to have stinted the 

 expenditure for the publishing of the Eeport, which, as regards 

 paper, print, plates of fossils, and coloured maps, has been brought 

 out very satisfactorily, and might be commended for imitation ta 

 Surveys nearer home. 



Mr. Anderson's field-work has been devoted mainly to a rough 

 survey of the province of Zululand ; in part to the coastal areas 

 on the east, and in part to the north-western border, where he has 

 been able to connect his work with that of Dr. Molengraaff in the 

 Vryheid district. The whole littoral area of Zululand, in places 

 50 miles in width, is uniformly flat or slightly undulating, some 

 areas swampy, others sandy, and largely covered with dense wood 

 or scrub. The rivers by which it is traversed cut deep into the 

 subsoils, but do not expose the rocks beneath as a rule. With 

 the exception of calcareous sandstones and conglomerates in two 

 or three small areas, the rocks shown on the coast are shales, marls, 

 calcareous beds, and lignites, with soft sandy deposits of all colours. 

 These are considered to be of Cretaceous age ; the only indications 

 of Tertiary rocks were some calcareo-arenaceous pebbles found on 

 the coast, which contained fragmentary Lithothamnion and numerous 

 Foraminifera, and an impure Diatomaceous deposit, near Lake 

 Sibayi, which may be of Pleistocene age. 



Mr. Anderson has also examined the Ecca series in the basin 

 of the Black Umfolosi, near the north - western boundary of
