86 REPORT OF COMMISSIONERS OF INLAND FISHERIES. 



was taken at the head of Narragansett Bay and was 25 mm. (1 inch) 

 in length as measured to the base of the caudal fin. The smallest 

 specimen which he figured in his report* was 32 mm. (1.3 inches). 



The two specimens referred to in this paper were taken in Mill 

 Cove, Wickford harbor, at the Experiment Station of the Rhode 

 Island Commission of Inland Fisheries; they were found in the 

 canvas bags which are used in the rearing of the young lobster fry. 

 One of these young squeteague measures 12.5 mm. {h inch) in length 

 to the base of the caudal fin; the greatest depth of the body was 

 3.75 mm. (.15 inch), which is 30 per cent, of the length; the eye was 

 about 1.2 mm. The other specimen was 6.5 mm. (.25 inch) in length, 

 and 2 mm. (.08 inch) in depth, which was a little over 30 per cent, 

 of the length; the eye was .7mm. in diameter. These measurements 

 were made after the specimens had been killed (one according to 

 Worcester's formula, the other in Zenker's fluid) and preserved in 

 80 per cent, alcohol, so that a very slight shrinkage may have taken 

 place. Along with these there were also taken about a dozen 

 others which ranged in size between the two mentioned above, and 

 which were apparently of the same species. Several of these were 

 kept in small cars until as late as October, during wdiich time they 

 become large enough to make certain the identification of these 

 fishes as young squeteague. 



The rearing bags used by the Rhode Island Fish Commission are 

 made of heavy canvas and are 10 feet square and 4 feet deep. Cir- 

 culation of water in them is maintained by a constantly revolving 

 paddle ^^•hich draws the water in at the l^ottom of the bag through a 

 window of wire screen and drives it out through similar windows 

 placed at two opposite sides. f These screens are made of copper 

 wire-netting of 20 meshes to the inch. These young squeteague - 

 then, could only have gotten into the bag by being drawn up through 

 the bottom screen when they were still small enough to pass through
