BIGELOW: COAST AVATER EXPLORATION OF 1913. 301 



clearly enough distinguished from allied species for its truly warm 

 water habitat to become apparent (Ritter-Zahony, 1911). Finally, 

 Eukrohnia hamata deserves brief mention. The Grampus has never 

 foi\nd it on the surface; and only rarely, and in small numbers in 

 hauls as shallow as 20 fathoms. But it was fairly numerous in the 

 deeps of the Gulf of Maine, (much more so than in 1912), and in the 

 deep hauls under the inner edge of the Gulf Stream (Stations 10064, 

 10076). As previously noted (1914a) it was to be expected in the 

 deeper layers, its range being from the surface in the arctic, to the mid 

 depths in low latitudes. 



TOMOPTERIS. 



The specimens of Tomopteris all belong to T. helgolandica Graeffe. 

 The records are from Stations 10057, 10058, 10068, 10069, 10082 

 10088, 10089, 10091, 10093, 10095, 10096, 10097, 10099, 10100, 10101, 

 10103; off Chatham, at Lat. 41° 48', Long. 70° 5' and at Lat. 41° 39', 

 Long. 69° 15'. Thus T. helgolandica was very generally distributed 

 in the waters of the Gulf of Maine and off New York; but it was not 

 found over the shelf south of New York, or in the Gulf Stream waters. 



Pteropods and heteropods.
