A critical consideration of several species of Charadrius. C. alexandrinus 

 seebohmi (p. 529) Aripo, northern Ceylon, is described as new and the type 

 of "JZgialitis homey eri " is shown to be made up of portions of two species. 



On Some Petrels from the North-east Pacific Ocean. By G. M. Mathews 

 and Tom Iredale. — As the authors state this is practically a ' remonograph- 

 ing ' of certain genera in the course of which Bannermania (p. 578) is 

 proposed as a new genus for Oceanodroma hornbyi, the type of which still 

 remains unique; also Cymochorea owstoni (p. 581), Yokohama Bay, Japan; 

 Puffinus bannermani (p. 594), Bonin Isl.; Neonectris griseus pescadoresi 

 (p. 602), Pescadores Isl.; N. g. missus (p. 603), Kuril Isl.; Bulweria 

 bulweri pacifica, (p. 607), Bonin Isl.; Calonectris (p. 592) for Puffinus 

 leucomelas; Microzalias, (p. 597), for P. nativitatis. 



Studies on the Charadriiformes. — I On the Systematic Position of the 

 Ruff {Machetes pugnax) and the Semipalmated Sandpiper {Ereunetes 

 pusillus), together with a Review of some Osteological characters which 

 differentiate the Eroliinae (Dunlin group) from the Tringinse (Redshank 

 group). By P. R. Lowe. — Both of these birds in osteological characters 

 are unquestionably members of the Eroliinoe whereas they have been 

 universally regarded as Tringine in their affinities.

Mr. D. A. Bannerman describes Dryoscopus angolensis cameroonensis 

 (p. 105) Cameroon Mountain; Dr. Van Someren proposes Apalis nigriceps 

 collaris (p. 107) from Uganda. 



Mr. C. F. M. Swynnerton discusses the coloration of eggs and the 

 mouths of nestlings, and suggests that to a certain extent these may be 

 due to protective mimicry. Certain eggs are found to be distasteful to 

 ' egg-enemies ' and others similarly colored may be cases of mimicry. The 

 coloration of the mouths of certain nestlings was considered as the possible 

 result of warning coloration. Mr. Stuart Baker opposed these theories.

 that the osteology of the bird showed distinct affinity to the Skuas. 



Mr. D. A. Bannerman presented a revision of the Puffinus kuhli group 

 describing as new P. k. fortunatus (p. 120) from the Canary Islands. He

 of Environment on the Evolution of Species."
