50 SUMMARY OF CURRENT RESEARCHES RELATING TO 



History Museum at Buenos Aires, of which he gives a list numbering- 

 nineteen, four of which deal with South American Protozoa. The 

 illustrations are admirable of their kind, the author admitting the lack of 

 certain details, arising from the fact that they are drawn direct under the 

 microscope from living specimens, and in no sense diagrammatic. His 

 method of technique was to check the movements of the organism by 

 means of " weak solutions of saliva or gum." Fifty species (none of 

 which are new) are described and illustrated : twenty-six in the order 

 Holotrichida, ten in Heterotrichida, and fourteen in Hypotrichida. The 

 author's descriptions show considerable discriminative power, and though 

 there is no marked new contribution to science the work is a useful and 

 praiseworthy addition to the literature of systematic protozoology.

Devonian Foraminifera. — Frederick Chapman (Froc. Linn. Sor. 

 N.S. Wales, 1918, 43, part 2, 385-94, pis. 39-42) describes fossil 

 Foraminifera from some micro-sections of the Nemingha horizon of 

 Oolitic limestones from the Tamworth series in New South Wales. Five 

 species are described, three of which are recorded as new — Psam- 

 mosphsera neminghensis, ValviiUna ohlonga, and Pulvinulina hensoni. 

 The author gives a resume of previous records of Devonian Foraminifera 

 from the Eifel (Terquem) and South Devon (Wethered). Chapman is 

 a micro-palffiontologist of experience and distinction, and any addition 

 to our knowledge of the Foraminifera put forward by him must command 

 attention, but it seems to us of doubtful utility to erect new species 

 upon the evidence of a few micro-sections. It is in the nature of a 

 reversion to the d'Orbigny system of nomenclature which is to be 

 deprecated. H.-A. & E.
