but tlie Eev. T. Hincks regards the identification as doubtful. It is 

 therefore of very great interest that the dredgings of the Academy- 

 should have brought the species to light again from practically the 

 same locality, and thus established the accuracy of Allman's identi- 

 fication. R. coiichii, Hincks, is new to Ireland. It is a southern 

 form, and has been recorded from only a few British localities. A 

 considerable number of fine colonies have been obtained from west of 

 the Great Skellig, of a larger size than any yet recorded from England. 



The British species of Crisia have lately been revised by Mr. 

 Harmer ; and, principally fi'om a consideration of the ovicells, he 

 places the identification of these otherwise difficult forms upon a 

 more secure basis. I have, therefore, mainly followed him in my 

 investigations of these collections, and have to record for Ireland all 

 the six British species he mentions, including the new species 

 C. ramosa, Harmer, which I have obtained from Dublin Bay. I have 

 to thank Mr. Harmer for having kindly verified my identifications of 

 this genus. 



The family of the Triticellidse calls for especial notice. The 

 south-west of Ireland is more fruitful in these forms than any other 

 locality. There are only four well-defined species in the family, 

 and one, SipjJuraria egertoni, Busk, is only known from Berehaven, 

 while the same locality has yielded to the Academy^ the first British 

 example of Triticella loechii, Gr. 0. Sars. The two other species, 

 T. horenii, G. 0. Sars., and T. pedicellata, Alder, are each only 

 recorded from one British locality ; but I have here to record them 

 from several Irish localities. The quantity in which these rare forms 

 have been obtained enables me to add a new generic character, 

 namely, the presence of a continuous horny crust from which the 

 peduncles arise. Considering the abundance and luxuriance of the 

 colonies obtained, as compared with any other locality, the south- 

 west of Ireland may be regarded as, par excellence, the home of the 

 Triticellidae. 



The genus Ascopodaria^ has been lately founded by Busk, in his 



1 Most of the specimens recorded from Berehaven in this and the following 

 Paper were actually collected hy Prof. Haddon after the close of the first Survey 

 in 1886. 



2 The genus Ascopodaria, which Eusk has founded and which Lomas employs, 

 has no claim to a place in the nomenclature of the Polyzoa. It was anticipated by 

 the name Barentsia, which Hincks had given to an Arctic form long before Busk's 

 name was published (Ann. and Mag. N.H. for October, 1880, p. 277). 



In his " Challenger " Report, Busk sets aside Barentsia in favour of his own
