EEPORT ON MAEmE ZOOLOGY. 



To EzEKiEL Holmes, M. D., 



and C. H. Hitchcock, A. M., 



Directors of the Scientific Survey of Maine : 



Pursuant to your instructions, I hereby submit the following 

 brief and partial report of my labors in the department of Marine 

 Zoology during the months of July and August, 1862. It is im- 

 possible to furnish anything more than a general statement of the 

 progress of the work, and of the portions of the coast visited, as 

 the proper identification and classification of the specimens col- 

 lected will require several months' additional labor. The time 

 allotted for my labors being but two months, and this in an 

 advanced stage of the season suitable for work upon the sea-shore, 

 I determined to commence at that point where the excessive fluc- 

 tuations of the tides were more favorable to an abundant growth 

 and a larger variety of species of marine life than some other por- 

 tions of the coast. 



Accordingly, on the eighth day of July, accompanied by Mr. 

 A. S. Packard, Jr., of Brunswick, I arrived at Eastport. Thence 

 I took my small skiff and selected Treat's Island as the most cen- 

 tral point of the work in that region, it furnishing the best advan- 

 tages on account of the extreme rise and fall of the tides, and its 

 proximity to deep water. From this place I made numerous excur- 

 sions by water to different localities, dredging in all practicable 

 places and in depths of water varying from fifteen to twenty-five 

 fathoms. 



Among the localities visited the following are the principal, and 

 the result of the dredging most interesting. 



At Treat's Island, between the high and low water marks, the 

 species of the fauna of the coast of Maine, mentioned below, occur. 



Sertularia polyzonias, S. argentea ; Ophiolepis robusta, Ophioph- 

 olis scolopendrica (plenty ;) Asteracanthion rubens, A. littoralis, 

 Solaster endeca, S. papposa ; Echinus granulatus ; Pentacta fron-
