Fishes of the Western North. Atlantic 205 



than 35—40 fathoms. Temperatures recorded for captures oi R. garmani have fallen 

 between 5.3° C (41.6° F) and 9.8-10° C (49-50° F) in the northern part of its 

 range to as high as i 5° C (59.1° F) in the southern part. The known salinities at which 

 it has been taken have also fallen within a narrow range: 33.8 "/oo off Block Island to 

 35.3 */oo off Chesapeake Bay. 



Range. Western North Atlantic from southern Florida to the offing of southern 

 New England in Long. 69°22' W, mostly on the outer part of the continental shelf 

 and the upper part of the continental slope. 



Details of Occurrence. R. garmani has been taken between the 30 and 290 fathom 

 contours 1" in the vicinity of the Tortugas; off the Florida Keys and Palm Beach, Florida; 

 off North and South Carolina; off Chesapeake and Delaware bays, and off southern 

 New England, a total of about 20 locality records. The fact that it has never been 

 reported among other Skates that are taken in abundance from the slopes of Georges or 

 the Scotian banks locates the eastern boundary of its regular range near the longitude 

 of Cape Cod or about 70° W. In the opposite direction, it appears that it does not cross 

 the Straits of Florida, for it was not represented among the extensive series of Skates 

 collected in Cuban waters by the Atlantis in 1 938-1 939. 



Along southern New England it is one of the most abundant of the Skates found 

 offshore. Thus we observed it in 2 i out of 44 hauls made in 47-67 fathoms between 

 Long. 71° 1 5' and 7i°54' W," in 12 out of 49 hauls in 41—240 fathoms between 

 Long. 67°io' and 72°2o' W."
