has adopted and extended Vine's suborder Cryptostomata for 

 their reception. The cryptostomatous zooecium is typically 

 ovoid, as in the Cheilostomata, with an aperture towards one 

 end ; but, as growth proceeds, the rim of this aperture is pro- 

 longed out into a calcareous tubular vestibule, the axis of 

 which is oblique to that of the zooecium. I cannot help think- 

 ing that, in the highlj^ keeled Fenestellids, the polypides per- 

 manently protruded themselves even beyond their vestibules, 

 and ultimatel}^ became surrounded by a membranous tube 

 which extended as far as the tegnien. Enough has been said, 

 however, to indicate the lines on which observation may 

 profitably proceed ; and I need scarcely add that I should be 

 grateful for the loan of any well preserved specimens from 

 Irish Carboniferous strata. The surface cannot be too greatly 

 ** encrusted " by what may seem an outer sheath ; the zooecia 

 and fenestrules may be entirely disguised by the meshwork of 

 a rude or a more delicate tegmen. The forms, moreover, with 

 well marked keels, or merely with lines of tubercles, all have 

 an important bearing on the evolution of the more elaborate 

 genera.

ZOOLOGY. 



ARACHNIDS. 



Nev\^ Irish Spiders from Londonderry. — During the latter lialfof 

 1894, 1 sent Mr. G. H. Carpenter some spiders from Magilligan, Wahvorth, 

 and Rathmullan. Among them he found specimens of eight species new 

 to Ireland: — Zora spiuimana, Cryphoeca sylvicola, Hahnia clegans, Ltpiyphantes 

 alacris, Tmeticus abnori/ns, Microneta viaria, Xysticiis ei-ratiais, and Hdiophaniis 

 Jlavipes.

INSECTS. 



Co. Dublin Hymenoptera, Captures in 1894. — Last summer at 

 Monkstown I found Pscii pallipes abundantly in burrows of Anobiuni and 

 other wood-boring beetles. Crabro pdtarms I took in great quantity at 

 Portmarnock, also C. ccphaJotcs and C. varius. C. dimidiahts, a new local 

 record, also occurred at Monkstown. C. pdtarius I met with in numbers 

 at Laytown, as likewise Oxybeliis jiitightinis, on the occasion of the joint 

 excursion of the Belfast and Dublin P'ield Clubs in June. 



H. G. CuTHBERT, Blackrock, Dublin. 



Orthezia cataphracta, Shaw, in Co. Dublin. — When collect- 

 ing at Howth on the 9th of last Marcli, I found several beautifully fresh 

 examples of the female of the curious Coccid Orthezia cataphrada, Shaw, in 

 moss, near the top of the cliffs, at the back of Lord Howth's demesne. 

 This forms the first note of the insect from Co. Dublin. I have also 

 taken specimens on Bray Head and near Dingle. As it has now been
