Ntjdibeanchiata. 



Goniodoris castanea, Aid. and Han. Dursey Sound. This rare 

 species has previously occurred only at Salcombe Estuary, Devonshire, 

 and Saltcoats, Ayrshire. G. nodosa, Mont. Dursey Sound ; Triopa 

 claviger, 0. F. Miili. Dursey Sound ; Thecacera, sp., Dursey Sound. 

 A full description of this form vrill be given : it appears to be inter- 

 mediate between T. capitata, A. & H., and T. pennigera ; Doto coro- 

 nata, Gmel., Bantry Bay, Eolis exigua, A. & H., Berehaven. The only 

 other recorded Irish locality is from Dublin Bay {Proc. Roy. Irish 

 Acad. (2) IT. Science, p. 529) ; but it is probably widely distributed, 

 having been overlooked on account of its small size and inconspicuous 

 colouration. Eolis coronata, Eorbes, Berehaven. Two varieties of this 

 species were obtained, both more or less orange in colour. 



Cephalopoda. 



Loligo media, Linn. Station lY., one specimen ; Station YII., two 

 specimens. 



Crui§tacea. 



OsTEACODA. 



As all the dredgings have not yet been thoroughly examined for 

 Ostracoda, the present list of species and details of distribution 

 must be considered as very incomplete. Already sixty-seven species 

 have been found, one of which, Kirthe glacialis, has not been pre- 

 viously recorded as occurring in the recent state ; and, in addition to 

 these, there have been foiu- species discovered, which are believed to 

 be new to science ; but as only one example of each kind has been 

 obtained, it is not desirable to speak with certainty until more 

 specimens have been found. 



Many of the species mentioned in this Eeport are found more or 

 less abundantly all round the British Isles, ^ and, in this case, their 

 distribution is not given. When, however, a species is not recorded 

 from a particular district, but occurs round the rest of the coast, its 

 absence from that district is noted. The great majority of the species 

 occur as Post-tertiary fossils, but only two of them, Cythere jonesii 

 and Cytheridea papillosa, have been found in Tertiary deposits. 



I have to thank Dr. Brady for the trouble he has taken in determin- 

 ing some doubtful specimens for me, more especially as several of them 

 were only single valves, and consequently more troublesome than per- 

 fect ones usually are. 



^ I have taken most of the facts of distribution from a Paper " On the Distri- 

 bution of British Ostracoda," by Messrs. Brady and Robertson, published in the 

 Annals and Magazine of Natural History ; but have also made use of Dr. Brady's 

 Monograph of the British Ostracoda, and other works on the subject.
