MUSEUM OF COMPARATIVE ZOOLOGY. 7 



Field work carried on during the year has contributed a large 

 amount of valuable material. This work may be briefly summar- 

 ized : — 



Mr. W. P. Haynes spent a week searching for fossil insects in 

 the Carboniferous area in the vicinity of Pawtucket, R. I. A 

 cursory examination of the material secured shows that plants, 

 crustaceans, and some tracks, possibly amphibian, were collected; 

 also a few fragmentary specimens that more careful study may 

 prove to be the wings of insects. While in the Rocky Mountain 

 region of Montana, Mr. Haynes also collected a large series of 

 Cambrian, Devonian, and Carboniferous invertebrates. This 

 collection was made mainly in the vicinity of Three Forks ; it is as 

 yet unstudied. 



By the courtesy of the Hon. G. M. Bowers, U. S. Commissioner 

 of Fisheries, the U. S. F. C. Schooner Grampus was placed at Dr. 

 H. B. Bigelow's disposal during July and August. Accompanied 

 by Messrs. W. W. Welsh and H. E. Metcalf as Assistants, Dr. 

 Bigelow undertook a partial survey of the Gulf of Maine. Forty- 

 six off-shore stations were occupied and a large number of in- 

 teresting observations relative to temperatures, salinities, currents, 

 and plankton were made; these will form the basis for a detailed 

 report. With the cooperation of Prof. J. S. Kingsley, a week was 

 devoted to trawling in Casco Bay and vicinity, but with this 

 exception little attention was given to work with the trawl or 

 dredge. The collections obtained by the Grampus, though rich 

 in a few groups, were not large. 



In two short trips, one to George's Bank and a second to eastern 

 and northern Maine, Mr. W. F. Clapp secured enormous series of 

 shells. The series from George's is estimated at 20,000 specimens 

 and that from Maine at 50,000. Some of the species collected 

 by Mr. Clapp are most desirable additions to the collection and 

 very many of the others provide specimens for advantageous 

 exchanges. Mr. Clapp's trip to George's was made on the trawler 

 Crest, Captain Green, through the courtesy of the Bay State Fish 

 Company. 



Dr. Thomas Barbour worked in western and central Cuba for 

 about two months, January-March 1912; he secured a large 

 number of new and little-known reptiles and amphibians as well 

 as other interesting vertebrates and invertebrates. He received 

 much kind assistance from Dr. Carlos de la Torre and Messrs. 

 R. M. Grey, Victor Rodiguez, and Jesus Valdivia.
