 A eegulae meeting of this section was held at 

 the American Museum of Natural History, April 

 11, 1910, Mr. Roy W. Miner presiding. The fol- 

 lowing papers were read: 



Collecting Inverteirates in the Woods Hole 



Region: Roy W. Minee. 



Mr. Miner gave an account of his collecting 

 experiences during the summer of 1910 in the 

 Woods Hole region. The methods and results of 

 a dredging expedition were first outlined, and 

 then the speaker gave an account of the habits 

 of some of the more interesting and typical in- 

 vertebrates found in the vicinity of Buzzard Bay 

 and Vineyard Sound, dwelling especially on the 

 Annulata. The address was illustrated with col- 

 ored lantern slides of the living animals. 



Osteology and Genetic Relations of the Meno- 

 typhloiis Insectivores : W. K. Geeqoey. (Read 

 by title.) W. K. Geeqoey, 



Secretary pro tern. 



At the regular meeting of this section held at 

 the American Museum of Natural History, May 

 9, 1910, Professor Bashford Dean presiding, the 

 following papers were read: 



Notes on the 'Insectivore Genus Tupaia and its 



Allies: W. K. Geegoey. 



In 1904 Dr. W. D. Mathew interpreted the 

 characters of many Eocene mammals of various 

 orders as pointing to a common stem form of 

 arboreal habits and structure. The oriental in- 

 sectivore Tupaia, and its little known Bornean 

 ally Ptilocercus loivii, serve to illustrate these 

 characters in still living forms. They nave a 

 divergent but not yet opposable thumb and great
