IO CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [Bull. 



sorted to as the numerous references will testify. The works of 

 Miss Richardson, especially her monograph on the North Ameri- 

 can Isopoda (Bull. U. S. Nat. Mus., -No. 54, 1905), of Oscar 

 Harger, and of G. O. Sars, have been very useful in the study of 

 Isopoda. Besides these, the classic Vineyard Sound report by 

 Verrill, Smith, and Harger (Rep. U. S. Com. Fish, for 1871-2, 

 pp. 295-747, 1874) and a Biological Survey of the Waters of 

 Woods Hole and Vicinity, by Sumner, Osburn, and Cole, (Bull. 

 Bur. of Fish., vol. 31, 1913) have proven mines of information 

 pertaining to the habits and natural history of the Arthrostraca 

 of Connecticut. 



The material upon which this report is based consists largely 

 of the collections of Amphipoda and Isopoda made by the 

 United States Fish Commission at Noank, Connecticut, in the 

 summer of 1874, and very kindly loaned by the Smithsonian 

 Institution, and the extensive collections in Peabody Museum 

 of Yale University, made mostly by Professors Verrill and 

 Smith in the neighborhood of New Haven. 



As might be expected, there are very few species from this 

 State which have not already been reported. Holmes in his 

 paper on the Amphipoda of Southern New England (Bull. U. 

 S. Bur. Fish., vol. 24, pp. 457-529, 1905) and in his key 

 to the Amphipoda of North America published in the 

 American Naturalist, (vol. 37, pp. 267-292) has reported all 

 the Amphipoda which have been found in Connecticut with 

 the exception of Photis reinhardi Kroyer, and one species 

 Tmetonyx quadratus which is here described and figured for the 

 first time. Miss Richardson has included in her key to the Isop- 

 oda of North America (Amer. Nat., vol. 34, pp. 207-230 and 

 295-309) all the species of Isopoda which we have met with in 

 the present study. 



Notwithstanding the fact that so few additions to the fauna 

 of New England are made in this report, it is hoped that the 

 publication of the figures of native forms, together with a gen- 

 eral account of the anatomy and biology of the Arthrostraca, 

 will stimulate interest in this group and be of service to students.
