of grown fish generally secured in collecting nets. From the difficulty experienced 
in recapturing adult fish placed in a rather large tank table in the laboratory, it is 
evident that nets are not very efficient for capturing the fish, because they attach 
themselves, by means of the sucking disk, to the bottom or to objects in the water, 
or they hide under objects, thereby making it very easy for a net to slide over them. 
They no doubt escape the net in a similar way in nature. All of this is a further 
indication that the fish probably are more numerous than shown by the number of 
adults captured. 
No evidence indicating that any one individual produces an excessively large 
number of eggs was secured. A female 25 mm long with a greatly distended abdo- 
men, for example, contained only 249 eggs. Furthermore, the eggs in the ovaries 
in several specimens examined were all of uniform size, indicating that a single spawn-

ing takes place during a season. The great abundance of the young — in several 
instances a hundred or more and in a few instances probably nearly a thousand 
specimens were taken in a single tow-net haul — then, would appear to be due to the 
presence of many adults. 
The local species of Gobiosoma, which rarely exceeded a length of 2 inches, 
obviously are too small to be of direct commercial value, yet they probably are 
of some importance as forage for commercial species. 
Notliing is known concerning the winter home of Gobiosoma. We have taken 
no specimens during the colder months of the year, or from early December to early 
May. It seems probable that these fish imbed themselves in mud during the winter. 
This probability is suggested by the abundance of gobies in seine hauls made in 
the Mullet Pond throughout the warmer months, in places where none were taken
