FALL AND WINTER EGGS IN OTHER PLACES. 



The conclusion that the production of eggs in the fall and winter is of general 

 occurrence throughout the entire range of the lobster is supported by the observations 

 recorded in table 13. Here are eggs, none of them laid during the summer months, 

 coming from a wide area from the middle and eastern parts of the Maine coast, from 

 the outward islands, and from the province of New Brunswick. They are compared, 

 as before, with the rate of development of summer eggs observed at Woods Hole 

 [lobster No. 3 (1) to (20), table 18]. In one instance, No. 20, the yolk is uusegmented, 

 though taken in February; in others the egg nauplius, which in summer appears at 

 about the fourteenth day, is barely outlined.

Mr. N. F. Trefethen, of Portland, who deals extensively in lobsters, and who has 

 a lobster pound in South Bristol, 35 miles east of Portland, believes that some lobsters 

 in that vicinity spawn in June. In support of this view he cited the following case: 

 In the latter part of May, 1893, he placed 20,000 lobsters in his pound and took them 

 all out at intervals in the month of July, beginning the first of the month. All the 

 lobsters had been examined before they were placed' in the pound, and none of them 

 were known to be with spawn. At the most only a relatively few egg-lobsters could 

 have been put into the pound by accident. When taken out about one-third of the lob- 

 sters had spawn attached to the body. It is thus evident that some of these females 

 must have laid their eggs in June or in the first part of July. No tally was kept of 

 the proportion of egg-lobsters taken out during the first part, the middle, aud the 

 latter part of July, and it is possible that the great number of egg-lobsters, which
