190 REPORT— 18G4.. 



taken by Mr. Barrett, in Shetland, from which alone the species has been 

 recognized as British, appears to have been lost. Three or four specimens of 

 Psolus squarnutas 'were taken off Holy Island. 



Amongst Polyzoa, Mr. Alder reports the following as being new to the 

 . coast : — Lepralia annulata and TuhuJipora hhidata. Bugida Murrayana was 

 abundant, and appears to be pretty nearly confined to the east coast. 

 Among Hydrozoa the most interesting captm-es were Tahiclava cornucopia} (a 

 new species lately described by Mr. Norman from specimens taken in Shetland), 

 Plumularia mt/riophyllum, a rare species new to this coast, and Halicium 

 labrosum. 



Several fine Sponges were obtained off Dunstanbro', but these and the Fora- 

 miuifera have not yet been examined.
