OF GAL WAY. 83 



tuation of surface is of no specific value, we have several speci- 

 mens of Z. hvvis^ L.faba, and L. bicariiiata^ which are distinctly 

 and regularly punctate. Had they been striate instead of punc- 

 tate, it would have been our duty to have given them distinctive 

 names. So much for the importance attached to the nature of 

 surface-ornamentation. 



OTHER FORMS. 



The NoDOSARiXE Forms in this gathering are few in number, 

 and present but little variety. 



Ramulixa. — This genus, as constituted by Professor T. Rupert 

 Jones, contained the so-called Dentalma acukata of d'Orbigny and 

 two species, R. Icevis and R. brachiata, discovered by our friend 

 Joseph Wright, F.G.S., in the chalk of the North of Ireland."^ To 

 these has been added a recent species, R. globulifera^ from the 

 "Challenger" dredgings, by H. B. Brady, F.R.S.f This last 

 author expresses surprise that such a true De?italina as d'Orbigny's 

 figure of D. aciileata appears to be, should be associated with any 

 Ramuline form. We have in our possession a slide obtained more 

 than twenty years ago from the late Professor Tennant, which bears 

 a printed label — " Dentahna aculeata (d'Orb.), Chalk-marl, Kent." 

 On this slide are four specimens of a subsegmented branching fora- 

 minifer, resembling d'Orbigny's species in having the surface acule- 

 ate, but otherwise bearing the Ramuline characters of the speci- 

 mens discovered by Joseph Wright. We mention this in order to 

 show that the error, if it be one, is of long standing. 



The Gal way material has yielded one specimen only of this 

 genus, Plate IV., Fig. 7. This appears to approach most nearly to 

 the R. Icevis of the Irish chalk. 



It is perhaps worthy of notice that many of the Ranmlince, in 

 form and texture, resemble the cervicorn outgrowths of certain 

 PolymorphifKB. 



LixGULiXA CARixATA, Plate IV., Fig. 6.— Of this rare species 

 two specimens "have occurred. The one figured has an entosole- 

 nian tube occupying the full length of the last formed chamber. In 

 two respects they differ from d'Orbigny's definition of the species, 

 inasmuch as they are not carinate, and the primordial chamber,
