102 PYRULA. 



which has usually beeu named as above, the spine is more 

 developed and the whorl more angular. 



12. cochlidium, f. 27, Linnceus. — Testa oblongo-fusi- 

 formis castaneo-fusca, laeviuscula, leviter spiraliter striata, 

 anfractibus turritis angulatis, supra angulum canaliculatis 

 depressis, infra angulum rotundis, ultimo magno, ad angulum 

 elevato carinato undulato, infra versus canalem coarctato. 

 — In general character and form approximating P. pugilina, 

 but having near the suture a channel formed by the de- 

 pression of the whorl and a raised parapet on the angle. 



13. Morio, f. 1, 2, Gmelin. — Testa magna elongato-fusi- 

 ormis nigrescens, fasciis albescentibus superne cincta, 

 spiraliter sulcata, spira exserta, anfractibus versus suturam 

 angulatis, plus minusve tuberculatis, ultimo versus canalem 

 attenuato ; apertura elongato-pyriformi. — This long blackish, 

 pyriform shell sometimes attains a considerable size, spe- 

 cimens in the British Museum being over a foot in length. 

 The variety, fig. 2, named Fusus coronatus by Lamarck, 

 is more broadly developed, and has very large tubercles on 

 the angle of the whorls; the whitish bands vary in number, 

 but are always few and are seen towards the upper part of 

 the more ventricose portion of the last whorl. 



14. colossea, f. 3, Lamarck. — Testa magna, elongato- 

 fusiformis, pallide carneola, tenuiuscula, longitudinaliter 

 striata, spiraliter distanter lirata et tenuiter interstriata ; 

 spira breviuscula anfractibus, superne angulatis, supra an- 

 gulum declivibus ; ad angulum acute tuberculosis ; ultimo 

 eleganter pyriformi, versus canalem sensim attenuato. — A 

 specimen of this large and elegant species in the British 

 Museum measures about fifteen inches. 



15. tuba, f. 9, Gmelin. — Testa P. colossei similis sed 

 brevior, lata, tuberculis longe majoribus, anfractu ultimo 

 infra medium coarctato, turn tumido, infra contracto. — Much 

 broader, shorter, more suddenly contracted towards the canal 

 than P. colosseus, with large angular tubercles at the upper 

 angle of the whorls. 



16. ternatana, f. 7, Gmelin. — Testa gracilis castanea, 

 spiraliter lirata ; spira producta turrita, anfractibus versus 

 suturam angulatis, ad angulum acute tuberculatis, ultimo 

 elongato-pyriformi, sensim versus canalem attenuato. — This
