area off the Isle of Man from about the end of February 

 to the first week in August. It probably occurs even 

 earlier than the end of February, as we have found it in 

 plankton collected in Ramsey Bay on the north-east end 

 of the Island on January 23rd. The eggs occurred in 

 Port Erin Bay on February 26th in 1907, which is the 

 earliest record obtained during the six years' investiga- 

 tions. It was noted in the open sea on March 7th. The 

 eggs were generally distributed in the Bay and in the 

 open sea during the whole of April. It was observed for 

 the first time in 1908 on April 2nd, and was present 

 throughout the month. It only appeared once in May, and 

 that was on the 26th, when forty specimens were found. 

 The eggs were generally distributed in the Bay in June. 

 It was captured on July 14th, and again on August 7th. 

 The first record for 1909 was obtained from plankton 

 collected in the Bay on March 5th. The egg was very 

 rarely absent from that date onwards to June 25th. It 

 appeared on March 15th in 1910, and was generally 

 distributed to the end of April. The eggs only occurred 

 once in May, on the 26th, but they were noted in the 

 collections taken on June 3rd, 11th and 24th, and on 

 July 8th, 14th and 26th. Dragonet eggs were first 

 obtained on March 2nd in 1911. They did not occur 

 again until April 10th, and were present during the 

 remainder of the month. None were taken after 

 May 1st. The eggs were more uniformly distributed in 

 1912 than in 1911. They were present in the plankton 

 of the Bay and open sea from March 4th right on to 

 June 3rd. Four hauls made with the shear-net at 

 Station III on April 12th, 18th, 19th and 22nd contained 

 141 eggs. The haul on the 12th April captured 73 of 

 this total. Although the dragonet eggs may disappear 

 from the plankton collected off the south-west of the
