Hab., Persian Gulf, Maskat, 15 fathoms. 



A most elegant Scala, with a somewhat familiar aspect, which, how- 

 ever, is not to be matched exactly. The spaces between the very 

 numerous, but compact, lamell?e are quite smooth. 



A few examples.

Scala cerdanta sp.n. (PI. VII., fig. 3). 



^S*. testa minuta, delicata, i/nperforata, oblongo-fusifonni, acuminata, 

 alba, nitida, Icevi, anfractibus noveni, quorum quatuor apicales, 

 attenuati, perlceves, albo-brunnei, hyalini, cceteris ad suturas impressis, 

 ventricosulis, Icevibus, undique tenuilamellalis, lamellis tenuibus, acutis, 

 supre hamatis, numero anfractum apud ultimum circa quatuordecim, 

 apertura ovato-rotunda, labro crassiusculo, albo, nitido. 

 Long., 4. Lat., 1-50 ;;/;;/. 



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

 A minute species, of the normal type, very delicate, not very closely 



whorled, the lamellas being bluntly hamate above. 



It is almost impossible to define in a cut-and-dry description many 



of the minute differences between shells of such a uniform pattern as 



the Scalce — the figures will best pourtray their various idiosyncracies. 

 (KcpSavTos, profitable). 



Scala confusa Sw. 



M.C. On the border-land towards India, 10 to 25 miles west of 

 Karachi ; also at Karachi and Manora Point. 



Scala continens sp.n. (PL VII., fig. 12). 

 S. testa imperforata, ovata, tenui, albo-lactea, apice acuto, anfractibus 8, 



quorum tres apicales, Icevissimi, vitrei, cceteris subventricosis, apud 



suturas excavatis, undique arete longitudinaliter lamellatis, lamellis 



concinne continuis, regularibus, acutis, temiibus, numero ultimum ad 



anfractum circa quatuordecim, interstitiis Icevibus, apertura ovata, 



labro nitido, tenui, paullum reflexo. 



Long., 4. Lat., 2 mm. 



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

 Also lat. 23° 55' N., long. 57° 48' E. 



This, the most abundant of the many species of Scala dredged at 

 the above soundings, bears a resemblance in the continuous lamellae 

 to S. clathrus L. It is a remarkably delicate and distinct form. 



(continens, continuous).
