Scala deifica sp.n. (PI. VII., fig. 4). 



S. testa attemiato-fusiformi, gracili, anguste umbilicata, delicata, albo- 

 hitea, anfractibus 9-10, quorian apiaxles 3-4, Icevissimj, pervitrei, 

 tiitentes, cceteris ad suturas impressis, ventricosis, arete longitudinaliter 

 lamel/atis, lamellis supra pukhre acu/eatis, regiilaribus, rectis, inter-

 Long., II. Lat., 4 ;;/;//. 



Hab., Gulf of Oman, lat. 24° 58' N., long. 56° 54' E., 156 fathoms. 

 India, Karachi, a small example. 

 If all the specimens we have sorted from the above two localities, 



large and small, belong to the same species, there must be considerable 



diversity of form, some being more ovate than others. The three large 



examples taken for the type, from the Gulf of Oman, are much alike, 



and all are similar in lamellae and sculpture. 



The lamella are not of the same character as those of S. laidlawi ; 



they are deeper, and distinctly aculeate, but the interstices in both 



species are equally beautifully striolate. 

 {deificus, divinely formed). 



Scala eclectica sp.n. (PI. VII., fig. 5). 



S. testa parva, umbilicata, ovata, albida, parum nitida, anfractibus sex, 

 quorum duo subhyalini, albo-brunnei, perlceves, cceteris ventricosis,

 continue, stibincrassato, nitido, albo, 

 Long., 5. Lat., 3-50 mm., sp. maj. 

 Hab., India, Karachi. 



A small species, with six whorls, of which three are tumid, beauti- 

 fully longitudinally lamellate, the interstices being smooth ; the last 

 whorl, provided with about forty lamellae, is very ventricose, the um- 

 bilicus is deep and well marked, outer lip thickened, white, shining.
