SYKES : NEW FORMS OF CATAULUS. 55 



Cataulus austenianus, Benson. 



Cataulus blanfordi, Dohrn. 



In my view G. connedens, Fulton (J. Malac, x, p. 102) 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 eollettl, Sykes. 



Cataulus deeorus, Benson. 



Cataulus eurytrema, Pir. 

 Cataulus greeni, Sykes. 



C. (jreeni, Sykes : J. Malac, vii, p. 30. 

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



Cataulus haemastoraus, Pn. 



A variety occurs with a white lip. 



Cataulus layardi, (Gr.iy) Pfr. 

 Cataulus marginatus, Pfr. 

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

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



Cataulus nevilli, Sykes. 

 Mr. Fulton has described (I.e.) a va.r. flaveolabris. 



Cataulus nietneri, Neviil. 

 Two varieties, unicolor and cajyerafa, were recorded by Collett 

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



Cataulus prestoni, n. sp. 

 Cataulus pyramidatus, Pfr. 

 The two forms mentioned by Pfeiffcr, scjm to occur in all collections. 



Cataulus rUgOSUS, Fulton. 

 Cataulus riujosa, Fulton : Ann. Nat rtis ., ser. 7, vol. xiii, p. 452. 

 Cataulus smith), n p. 

 Cataulus sykesi, Fuiion. 

 Cataulus templemani, Pn. 

 Cataulus thwaitesi, I'lV. 

 1 am unable to clear ui) the relationships of this forai with the shells 

 fljscribed by Pfeiffer under the names of n. iiintji and ihiplicatux, but I 

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

 species.
