SOLENOGASTRES FROM THE EASTERN 

 COAST OF NORTH AMERICA. 



INTRODUCTION. 



The present report deals with a collection of upwards of one hundred 

 and twenty-five Solenogastres dredged at various times by Coast Survey or 

 U. S. Fish Commission vessels along the eastern coast of the United States. 

 The greater number of these were placed at my disposal by the late Mr. 

 Alexander Agassiz, who generously granted permission to include the descrip- 

 tions of additional species based upon material kindly forwarded by Prof. 

 A. E. Verrill and by the officials of the National Museum. 



The territory embraced by these explorations, with the exception of a 

 single station off the south coast of Florida, another in the Gulf of St. Lawrence 

 and a third off the coast of Newfoundland, extends from the Gulf of Maine 

 on the north to the mouth of Chesapeake Bay on the south. The larger num- 

 ber of dredge hauls were made along shore in comparatively shallow water; 

 thirty-four were at depths ranging from one hundred to five hundred fathoms, 

 three were from five hundred to one thousand fathoms, two from one thousand 

 to fifteen hundred fathoms and one from seventeen hundred and fifty-three 

 fathoms. The appended table indicates the habitat with greater exactness. 

 The following abbreviations have been employed to indicate the vessels engaged : 

 A Albatross, B Bache, Be Blake, Bt Bluelight, Fk Fishhawk, Sp Speedwell.
