FAIRBANKIA (?) FEDDENIANA, n. Sp. 



Imperforate, solid, turretly conoidal, white, upper whorls subacutely, 

 spirally striate, striation on the last two whorls more or less obsolete, 

 imparting a " quasi" malleate appearance. Spire turreted, apex broken off 

 in all the specimens seen, suture very distinct ; 5 whorls remaining, probab- 

 ly there would be about 8 in a quite perfect specimen, scarcely convex, 

 increasing regularly and slowly in size, the last whorl produced at base ; 

 aperture rather small, subquadrangular, nearly perpendicular, moderately 

 dilated at base, outer lip not reflected, bordered with a very broad and 

 callous rib, columellar margin perpendicular, distinctly subangulate above 

 and below, margins joined with a thick callosity. 



Long. 6 (vix), diam. 1\ mil. (anfr. 5 only). 



Type, Indian Museum ; also in coll. Fedden. 



I am indebted to Mr. F. Fedden of the Geological Survey of India 

 for an opportunity of describing this interesting form ; one of the specimens 

 is from the coast of Kathiawar, all the others are part of a small, but 

 remarkable collection made by the above mentioned gentleman " 10 feet 

 below the surface of the Littls Rann, at the Kura salt works in northern 

 Kathiawar."
