2 Smith and Harger — St. George's Banks Dredgings. 



After we were obliged, late in September, to leave the expedition. 

 Prof. A. S, Packard, Jr., and Mr. Caleb Cooke, of Salem, Mass., went 

 in the steamer on another trip, which was mainly devoted to dredg- 

 ing. On this trip a number of successful hauls were made at differ- 

 ent localities along the northern extremity of George's Bank, in 40 to 

 150 fathoms. The region visited on this trip was quite distant from 

 any of the localities examined by us, and the bottom, in the deeper 

 dredgings, was of an entirely different character, so that the collec- 

 tions made by Prof Packard and Mr. Cooke contain many species 

 not found by us, and add very greatly to the value of the results. 



We wish specially to acknowledge the assistance rendered us in 

 the preparation of this report by Professor Verrill, who has identified 

 all the worms mentioned, and the more difficult mollusks and 

 radiates. 



The following table will facilitate references to the localities at 

 which the dredgings were made. The letters in the first column are 

 the same as those used by Professor Verrill in his papers in the 

 American Journal of Science. When more than one haul of the 

 dredge was made at any of the localities, the number of hauls is indi- 

 cated in parenthesis. 



The first dredgings were made on the evening of August 29, to the 

 west of George's Shoal, about latitude 41° 40' north, longitude 68° 10' 



* Very little confidence can be placed in these bottom temperatures, as the Miller- 

 Casella thermometers used did not give uniform results. Most of the temperatures 

 are manifestly much too high,
