36 A. E. Verrill—Results of recent Dredging 
This table is taken from Key West; my observations were 
at ee Tortugas) There may be differences in the amount and 
the curve of variation in different places. But this would 
idle but little difference in the result. I believe we ma 
say with confidence that the annual growth of madrepore 
points in the Gulf is not more than 34-4 inches per annum.

Yale College. No, XXXIII.— Results of Dredging Rasedeons 
off the New England Coast in 1874; by A. E. VeRRIbu. 
In the last number of this Journal a penaral statement was 
made of the operations in connection with t . Fish Com- 
mission, located during the summer of 1874 at Noank, Con- 
necticut, on Fisher’s Island Sound, and close to the eastern 
end of Long Island Sound 
In the following article only a brief summary of the results 
can be given; the full details will eventually appear, however, 
in the report of the Commissioner. 
The total number of recorded stations, where dredgings 
were made during the summer, is 180. but many others, not 
re , were made by members of the party. A large 
number of additional localities along the shores and in the 
shallow waters of the harbors were explored by hand nets and 
otherwise with excellent results. Temperatures were not taken 
at all the dredging localities, and therefore, in the accompany- 
ing table, such localities have been, for the most part, omitted. 
The localities dredged may be conveniently grouped as 
follows 
a. Bisbee Tsland Sound, enone hard gravelly and ston 
bottoms, often rocky, and occasionally with some sand or set 
the depth varying from 4 to 15 fathoms. The tidal currents 
were rather MTOR and the bottom temperatures were lo 
— 61° to 65° F.). 
Block Island Pace including a wide region from off 
end Judith, R. I o Race Point, -at the western end of 
Fisher's Island ; the topil varying from 5 fathoms or less to 
upwards of 40 fathoms, near Race Point (No. 45). The cur- 
rents are strong, especially toward Race Point, and the temper- 
atures are low (56° to 64°). The bottom is generally gravelly, 
stony, or sandy, occasionally rocky, and but seldom muddy. 
An extensive “scollop-bank” (Pecten tenuicostatus) occurred in 
18 to 22 fathoms, south of Watch Hill, where many interesting 
species were found, among which was 8 CO 
ome uae living, is of a beatifal vilteslor (rarely brownish) 
there are six rays. 1 6 aiid wk totter Suaile epecien, Oe
