begun in February and continued throughout the year. 

 The tow-nettings for February comprised eight surface 

 and five bottom samples. Copepoda, so far as number 

 of species go, readied the maximum point in this month, 

 when fourteen forms were noted, but only four of these 

 (the same as in January) were at all common. Sagitta 

 was again abundant near the bottom. Copepod nauplii 

 and the nauplii of barnacles made their appearance in 

 February. Seven species of fish eggs were noted and 

 two species of diatoms. Five other coastal areas were 

 examined, one off-shore station and Port Erin. Diatoms 

 appeared to be scarce in distribution throughout the Irish 

 Sea. Three genera were represented at Port Erin, two in 

 Cardigan Bay and one in Fishguard Bay. Altogether 

 thirty distinct organisms were detected in Cardigan Bay. 

 Port Erin, with fourteen, was the next richest area. 



In March owing to pressure of other work the 

 steamer was unable to investigate Cardigan Hay, but the 

 Fishery Officers sent in five samples, which were repre- 

 sentative of the whole month. Twenty-three organisms 

 were noted, including eight species of Copepoda and five 

 species of fish eggs. The ostracod stage of barnacles and 

 the v<y^^ of species of Ascidians appeared for the first 

 time in 1905 in this month. Five coastal areas were 

 investigated, also four stations in the central portion of 

 the Irish Sea. but Port Erin was not represented. 

 Diatoms were apparently present throughout the whole 

 of the Irish Sen in March, and were represented by the 

 genera Biddidphia and Coscinodiscus. 



The steamer was again engaged in other work in 

 April, and the collections sent by the Fishery Officers 

 contained the only material available. These were 

 taken on the 12th, 18th (two tow-nettings | and 29th. 

 The organisms numbered twenty-live, and included six
