NEWS NOTES 133 



Augustus L. Clarkson has given the Museum a collection of 

 insect architecture and the entomological library formed by his 

 brother, the late Frederick Clarkson. The collection consists of 

 two large cases containing a popular display of the well-known 

 insects, their homes, food and, to some extent, their life history. 

 These cases have been installed beside the entrance of the Hall 

 of Entomology (No. 307 of the Third Floor). 



The observation hive of the Honey Bee has been placed in 

 position in the hall of Entomology (No. 307 of the Third Floor), 

 and its occupants may be watched at their honey making every 

 day. 



The Department of Conchology has received from C. D. 

 Guyer some well-prepared specimens of the local molluscan fauna. 

 The specimens include exquisitely cleaned individuals of Petricola 

 pholadiformis, Lam., and Pholas tunicata, Say, both taken at 

 Barren Island, in crowded colonies, in hard resistant submerged 

 turf beds. From the Bronx River and from the lake in Prospect 

 Park, Brooklyn, Mr. Guyer obtained large and living examples of 

 Unio and Anodonta. Ensatella americana Gould, in perfect 

 condition, with uninjured epidermis, was also received from Long 

 Island, through the same collector. The Pholas showed the 

 supplementary valves uninjured ; and the Petricola which, urJess 

 carefully treated, will so compress its valves as to crack and dis- 

 figure them, was also perfect. 



The Bruce Fund continues to augment the mineral collection, 

 and in the last few months has added some interesting Silvers 

 from Cobalt, Ontario, Canada, among which are the curious 

 antimonial bodies, which seem to grade into true Dyscrasite on 

 the one hand, and into pure Silvers on the other. Together 

 with these was obtained a remarkable specimen showing a vein- 

 let of native Bismuth between walls of calcite. 



A STRIKING Silver from Lake Superior, Michigan, associated 

 with Copper, Calcite and Epidote, is quite unlike the other Silvers 

 in the collections from the same region, being composed of rough 

 and twisted sheets implanted in the rock and rising from it in 

 broken folice.
