Fig. 45, /'. Mus. Brit. A much more fully developed 

 shell than that figured in the seventh plate. 



Species 70. (Mus. Brit.) 



ScALAKiA MlNOl!. Sca. tcsl/i turritd, (p-acili, pallide 

 fitho spiraliter hifasciatd ; sjiira cloiujatd ; arifrac- 

 tibus nbliquis, jirominentibtis, siipi-d siiba^iffii/ntiif, 

 infra spiraliter nnicostatis, infra cosiam castaneis, 

 longiindiiialiter oblique et arcuatim lirutis. 



The minou Scalaria. Shell turreted, narrow, with 

 two spiral bands of pale brown ; spire elongated ; 

 whorls oblique, prominent, slightly angular above, 

 with a single spiral rib at the lower part, chest- 

 nut below the rib ; longitudinally obliquely and 

 sinuously ridged. 



SOWERBY. 



Acrilla gracilis, A. Adams. 

 ffab. Mouth of the Indus. 



The name gracilis having been already applied to 

 another Scalaria, cannot be applied to the present 

 species if included in the genus. Would it not be bettor 

 in separating small groups from old genera, to avoid 

 using specific names already applied to shells belong- 

 ing to those genera ? A crilla may be a very good 

 genus, but its adoption should be left optional, by 

 not using a specific name already occupied in the old 

 genus. 



Species 71. (Mus. Brit.) 



Scalaria atti:xuata. Sca. testa parvd, angnstd, al- 

 bidd ; spird elongatd, atte7iiiatd ; anfractibus aids, 

 obscui-issime biangulatis et nodofis, siituris crenu- 

 lato, foveolatis ; idtiiao anfractu niagis pronnmnti, 

 distincte nodoso-biangulato : apirturd rotvndd, 

 labia exierno C7-asso, expanse. 



The attenuated Scalaria. Shell small, narrow, 

 whitish ; spire elongated, attenuated ; whorls 



elevated, very obscurely biangular and nodose, 

 suture crenulated, pitted; last whorl more pro- 

 minent, distinctly nodosely biangukited ; aperture 

 rounded ; outer lip thick, e.xpanded. 



Pease. ? 



Ilab. Sandwich Islands. 



This species very nearly resembles Scalaria bica- 

 rinata, Sowerby. It is, however, narrower and more 

 tapering, and the keels on the last whorl arc nodose 

 and much less distinct. 



Species 72. (Mus. Brit.) 



Scalaria Bairdii. Sea. testd ^xirvd, subcoeruled, lavi- 

 gald, pyramidatd ; anfractibus novem, altis, media 

 Icevigatis, supra infrdque plicatis ; plicis ad sii- 

 turam in nodes elevatis, interstitiis foveolatis : 

 aperturd parvd, ovatd, labia externa rotunda. 



Baird's Scalaria. Shell small, bluish, smooth, pyra- 

 midal; whorls nine, elevated, smooth in the 

 middle, plicated above and below ; plaits raised 

 into knobs at the suture, interstices pitted ; aper- 

 ture small, ovate, outci- lip rounded. 



Smith. Proc. Zool. Soc, 1.S71. 



Hab. Whydah, South Africa. 



This pretty little species is among some very inte- 

 resting shells brought by Captain Knocker from South 

 Africa, and described by Mr. E. Smith of the British 

 Museum, whose advent we welcome as a working con- 

 chologist. 



Species 73. (Mus. Brit.) 

 Scalaria Miranda. Testd parvd, subvmtricosd, fulvo- 

 subca:ruled, inter varices spiraliter tenuissime 

 striatd ; spird acuminatd, anfractibus octo, rotundis, 

 ultimo anfractu subinflato ; varicibus creberrimis, 

 tcmiissimis, laminatis ; aperturd ovatd, columella 

 erased, arcuatd, labia extcrno tcnui.
