species. The illustrations consist of photographs of specimens and groups 

 in the Colorado Museum of Natural History. A good plan for showing 

 the actual and relative size of the species consists of a photograph of a 

 series of skins, one of each species, arranged side by side on a sheet of paper 

 ruled with horizontal lines one inch apart. The pamphlet is well printed 

 and forms an attractive and useful publication. — W. S. 



Cassinia for 1917. ! — The Delaware Valley Club's annual publication 

 appears as usual in April covering the proceedings of the year 1917. The 

 leading article is a biographical sketch of Samuel Wright, one of the active 

 members of the Club who died early in the year, by Witmer Stone, with 

 portrait. Then follows an admirable review of the summer bird-life of 

 Pocono Lake, Pa., by John D. Carter; one of those boreal ' islets ' in the 

 mountainous part of the state which for many years past has been a 

 favorite resort for several members of the Club. The nest of the Golden- 

 crowned Kinglet found by Mr. Carter in 1916 was one of the latest dis- 

 coveries, the first actual nesting record of this species for the state. Samuel 

 Scoville, Jr., writes of the influx of Evening Grosbeaks which marked the 

 winter of 1916-1917 and brought this species within the Philadelphia 

 district for the first time. The usual migration report based upon the 

 schedules of fifty-one observers, and the abstract of proceedings complete 

 the number. 



The average attendance at the sixteen meetings held during the year 

 was twenty-one, notwithstanding the fact that twenty-two of the members 

 are in the national service. — W. S. 



Bangs and Penard on a Collection of Surinam Birds. 2 — This 

 paper is based on a collection of 2000 skins representing 301 species which 

 was made for the Museum of Comparative Zoology under the direction of 

 Mr. A. P. Penard, of Paramaribo, the greater part of the specimens being 

 obtained in the immediate vicinity of the city. 



There is a brief introduction in which the physical features of Surinam 

 are described, the country being divided into three parallel zones, the 

 alluvial lowlands, the savanna lands and the highlands stretching back 

 to the Tumuchumac Mountains of Brazil. Much of the last area is unex- 

 plored and according to the authors the extreme difficulties to be overcome 

 make it unlikely that any extensive work will be done there for some time 

 to come. 



Under many of the species there is a mere mention of the specimens 

 contained in the collection while under others there is considerable dis-
