276 LIVERPOOL MARINE BIOLOGY COMMITTEE REPORT. 



Port St. Mary and Spanish Head, Isle of Man, from a depth 

 of twenty fathoms. 



Tergipes despecta, Johnston. 



Several specimens of this small Eolid were found on June 

 13th by the L. M. B. C. adhering to Zoophytes at the north 

 end of Hilbre Island, near low-water mark ; the small 

 kidney-shaped masses of spawn were abundant. It was 

 found again at Hilbre Island on July 11th. 



The species has been recorded from G-arth Ferry, Bangor, 

 North Wales, by Alder and Hancock ; and from the Mersey 

 by Collingwood. 



Tergipes exigiia, Alder and Hancock. 

 This species was found along with the preceding one at 

 Garth Ferry, Bangor, North Wales, by Alder and Hancock. 

 It is also recorded by Dr. Collingwood as being rare in the 

 Mersey. 



Emhletonia pallida, Alder and Hancock. 



This rare species was discovered amongst seaweed on the 

 shore at Birkenhead in the spring of 1854, and sent for 

 description to Messrs. Alder and Hancock. 



As the Nudibranchs are not included in the distributional 

 tables of the Mollusca on pp. 247 to 266, a table is here 

 appended showing the distribution of the above noted species 

 in the three parts of the L. M. B. C. district in which they 

 have been collected and recorded. The first column includes 

 Hilbre Island ; and the second takes in the entrance to the 

 Menai Straits and the coast of Anglesey. 



Probably the greater number of species recorded from the 

 Mersey district is mainly due to that region having been so 

 thoroughly investigated by Mr. Price, Mr. Byerley, Dr. 

 Collingwood, and other naturalists of this neighbourhood.
