DESCRIPTIONS OF SIXTY-E1GIIT NEW SHELLS. 229 



Doubtless allied to D. boJwlensis, Reeve, but possessing two more -whorls, 

 while it is more graceful and attenuate throughout ; peristome not so effuse, 

 canal more prolonged, and spiral liration more distinct and regular. Again, it 

 differs in its beaded liration from any form of D. axis, Reeve, which it resem- 

 bles in form, and which also occurs in the same seas. Were it not for the 

 absence of columellar plication, it would more than resemble a Mitra of the 

 subgenus Concilia. The peculiar beauty well merits for it the specific name 

 proposed, of one of the three Graces. 



CYTHARA ELEGANTISSIMA, sp. n. (PI. D. fig. 13.) 

 C. testa pergracili, fusiformi, albida ; anfractibus 6, quorum 2£ apicales obtusi 

 plani, minute sculpti, cseteris supra medium tenuiter angulosis, dein rectis, 

 undique longitudinaliter rudiliratis, liris inconspicuis, spiraliter liris crassi- 

 oribus succinctis (in ultimo circa 14) ; apertura anguste oblonga, intus alb labro 

 sinu lato, haud prof undo, incrassato ; columella fere recta, basi prolongata. 

 Long. 8, lat. 2*50 mm. 



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

 25° 30' N., long. 57° 30' E., 88 fathoms, mud. 



A very elegant form, as implied by the specific name, with markedly obtuse 

 apex, probably not quite full-grown. The coarse longitudinal lira), crossed by 

 more distinct, but equally rough, spirals, are characteristic. Very rare. Since 

 description, another example has been procured, with perfect thickened lip, 

 sinus broad and shallow. 



CANCELLARIA (TRIGONOSTOMA) LUSCINIA*, sp. n. 

 (PI. D. figs. 14, 15.) 

 C. testa parva, attenuato-fusiformi, tenui, albida, vol pallid e olivaceostraminea ; 

 anfractibus septern, quorum tres apicales tumidi, vitrei, perlarves, ceeteris 

 longitudinaliter irregulariter sed arete costatis, ad suturas excavatis, costis 

 crassiusculis, undique transversirn tenuiliratis, liris tenuibus superficiem totam 

 circumambicntibus ; apertura oblongo-ovata, margine columellari triplicato. 

 Long. 11, lat. 4 mm. (sp. maj.). 



Hab. Arabian Sea, lat. 18° 58' N., long. 71° 45' E., 40 fathoms. 

 This is the little species alluded to by us in our former paper as having been 

 dredged near Bombay, as above, in April 1901. It is allied to C. macrospira, 

 Ad. and Rve., but much smaller in every detail. The shell is attcnuatcly spindle- 

 shaped, thin, cither translucent white or pale straw-olive, seven-whorled, the 

 three uppermost whorls being glassy, globular, and swollen, the remaining three 

 or four closely but irregularly ribbed, somewhat excavate, as are nearly all the 

 section Trigono stoma of Cancellaria, suturally. The transverse lira) surmount 

 the ribs and are not interrupted. The columella is thrice-plaited. 



KLEINELLA SYMPIESIA^, sp. n. (PI. D. fig. 1G.) 

 K. testa perforata rotundato-ovata, alba, obesa, compressa ; anfractibus 5, 

 quorum 1^ apicales vitrei, perlasves, cseteris apud suturas gradatulis, ventrico-
