EICINULA.— Plate IV. 



Species 28. (Mus. Cuming). 



KiciNULA FISCELLUM. Ricin. testa omtd, spird acuta, 

 anfractibus superne subamjulaik, ad angidum compres- 

 so-tiodosis, Uris augustis minute squamatls undique cre- 

 bmrime cingulatis ; albidd, Uris purpiireo-atris, cotii- 

 meUd et aperturre fauce purpnreo-violaceis. 

 The little basket Eicinula. Shell ovate, spire sharp, 

 whorls somewhat angulated round the upper part,

 f. 1524-5. 

 Murex margariiicola. Broderip. 

 Hah. Australia and the Pacific Islands. 



It will be seen on reference to genus Murex of this 

 work, that a most unhappy state of confusion has attended 

 this species on the part of Mr. Broderip, IVIr. Sowerby, and 

 myself. Named Murex margariticola by Mr. Broderip 

 from the circumstance of Mr. Cuming having found it 

 adhering to the Peaii Oyster (Conch. Icon. Murex Sp. 

 178.), another shell was fixed upon by Mr. Sowerby, and 

 adopted by myself, as representing the M. fiscellum of 

 Chemiitz (Conch. Icon. Murex Sp. 124.). The former is 

 however the true M. fiscellum, and the latter an extremely 

 variable species, again described by me in a different 

 state under the name of M decussatus (Conch. Icon. 

 Murex Sp. 153) ; though introduced by Mr. Sowerby 

 also in different states under the names of M. violacea anil 

 Rwiimtoides, which he afterwards cancelled. 



It is determined beyond doubt that the Murex mar- 

 gariticola of Broderip, of which the specimen here figured 

 IS a fine large tubercled variety, is the Murex fiscellum ; it 

 only remains to enquii-e of M. Kiener whether the sheU 

 mistaken for it, and wliich has received so many names in 

 difterent states, is not the Murex fimiriatus of Lamarck. 



Species 29. (Mus. Cuming.) 

 Eicinula forticostata, Ricin testa ovatd, medio gibbosd. 



longitudinaliter conspicue costatd, costis fortibus, vuU 

 promineidibus, sulcis decussatis ; albidd, costis fuscis 

 Uris decussantibus albidis. 



The strong-ribbed Eicinula. SheU ovate, gibbous ii 

 the middle, longitudinally conspicuously ribbed, 

 ribs strong, very prominent, crossed with grooves ; 

 whitish, ribs brown, the cross ridges white 



Ifai. ? 



The prominent character of the ribs, coupled with their 

 conspicuous style of painting, give an appearance to the 

 shell wliich is very characteristic. 



Species 30. (Mus. Cuming.) 

 Eicinula astricta. Ricin. testa ovatd, medio obesd, 

 solidd, utrinque attenuatd, longitudinaliter plicato- 

 costatd; Intescente-albd, Uris transversis angustis fuscis 

 undique pecuHariter astricta. 

 The corded Eicinula. Shell ovate, stout in the 

 middle, soUd, attenuated at both ends, longitudinally 

 plicately ribbed ; yellowish-white peculiarly corded 

 throughout with brown narrow transverse ridges. 

 Hab. ? 



Easily distingiushed by the fine dark bro^vn cord-like 

 ridges with which it is encii-eled throughout. 



Species 31. (Mus. Metcalfe). 



Eicinula ochrostoma. Ricin. testa ovatd, crassd, 

 concentrice plicato-costatd, costis Uris )wdosis decus- 

 satis, interstitiis minute squamafis ; alhd, apertura 

 fauce croceo-aurantid. 



The yellow mouth Eicinula. SheU ovate, thick, con- 

 centricaUy pUcately ribbed, ribs crossed with noduled 

 ridges, the interstices between which are minutely 

 scaled ; white, interior of the apertm-e saffron-orange.
