SYKES : NEW FORMS OF CATAULUS. 55 



Cataulus austenianus, Benson. 



Cataulus blanfopdi, Dohm. 



In my view 0. coniierfms, Fulton (J. Malac, x, p. 602) is only a local 



race with a yellow peristome : indeed I have specimens, which I am unable 



to sever from this species, in which the usual dark red peristome is here 



white. 



Cataulus congener, n. sp. 



Cataulus eoUetti, Sykes. 



Cataulus decorus, Benson. 



Cataulus eupytrema, Pfr. 



Cataulus greeni, Sykes. 



C. yreeiii, Sykes : J. Malac, vii, p. 30. 

 Mr. Fulton has (J. Malac, .x, p. 102) described a var. rolmata. 



Cataulus hieraastomus. Ph. 



A variety occurs with a white lip. 



Cataulus layardi, (Giayi Pfr. 

 Cataulus mapginatus, Pfr. 

 Mr. Fulton has described (Ann. Nat. Hist., ser. 7, vol. xiii, p. 453) a 

 variety erenulata. I take this opportunity of describing a remarkable variety. 



Cataulus nevllli, Sykcs. 



Mr. Fulton has described (I.e.) a \iir. Jlarc(j/ahriti. 



Cataulus nietneri, Ncviil. 



Two varieties, unirolor and raj m' rata, were recorded by Collett 

 (J. Malac; vol. vii, p. 85). 



Cataulus ppestoni, n. sp. 

 Cataulus pyramidatus, Pfr. 

 The two forms mentioned by Pfciffer, seem to occur in all collections. 



Cataulus rugosus, Kuiton. 

 Cafaii/us ri/<_/(i.<a, I'ulton : Ann. N.U. Mist., ser. 7, vol. xiii, p. 452. 

 Cataulus smithi, n. sp. 

 Cataulus sykesi, Knii'ni. 

 Cataulus templemani, I'fi. 

 Cataulus thwaitesi, I'fi. 

 I am unal)le to clear up the relationships of this form with the shells 

 described by Pfeiffer under the names of oojiiw/i and duplirafics, but I 

 incline still to the view that all three are probably varying forms of one 

 species.
