Woodlice of Ireland.*— Denis R. Pack Beresford and Kevin 11. 

 Foster record twenty-five species in twelve genera, and give an account 

 of what is known of their distribution in Ireland. They also give a 

 diagnostic key of the genera. 



New Carboniferous Crustacean. f — W. T. Caiman describes Pleitro- 

 caris annulatus g. et sp.n. from the English Coal-Measures near Dudley. 

 The possession of a "tail-fan," consisting of a pair of biramous appen- 

 dages on either side of a median telson, shows at once that it belongs 

 to the Malacostracan Crustacea and to the series Eumalacostraca. The 

 absence of a carapace practically narrows the comparison, among the 

 existing groups of Eumalacostraca, to the Isopoda and the Syncarida. 

 Reasons are given for referring Pleurocaris provisionally to the division 

 Syncarida in the vicinity of the genus Acanthotelson Meek and Worthen. 



Barnacles from Irish Seas.J — N. Annandale describes the external 

 characters of Scalpellum (Smiliuni) kempi sp. n., a peculiar species found 

 attached to Lopliolielia. It is apparently most nearly related to S. gemma 

 and S. grimdldi, but has two extra valves below the rostrum and a 

 narrower carina. The commonest species of the genus is S. vulgare, and 

 S. velutinum also occurs. In regard to the latter, the author notes that 

 it is closely related to S. fornix of the Italian Miocene, that it is common 

 on both sides of the Atlantic in northern latitudes, and has been taken 

 as far south as Tristan d'Acunha. It also occurs in the Indian Ocean. The 

 bathymetrical range is extraordinary — from 35 to over 1000 fathoms. 



New Ascidicolous Copepod.§ — E. Chatton and E. Brement describe 

 Ophioseides abdominalis sp. n., a parasite of Amaroucium densum, nearly 

 related to O.joubini Ch. Only the female is known, a vermiform, sub- 

 cylindrical, greenish-yellow animal with a bright red eye. 



Annulata. 



Oligoehaet Commensals in Spongilla carteri.|| -J. Stephenson 

 reports the occurrence of numerous fresh-water worms in a fresh-water 

 sponge. He calls the association commensalism, but does not give clear 

 evidence of the appropriateness of this term. One specimen of Prist 'in a 

 longiseta was obtained ; the others were referred to Nais pectinata sp. n., 

 N. communis Piguet var. punjabensis, and N. communis Piguet var. cseca 

 var. n. The last two are identical, except that the one has eyes and the 

 other has not. 



Bothrioneurum iris. 11 — J- Stephenson re-describes this interesting 

 earthworm from Kurseong in the Eastern Himalayas. It was first de- 

 scribed by Beddard from the Malay Peninsula, and afterwards examined 

 by Michaelsen from Kurseong. The pear-shaped spcrmatophores are
