8. TEREBRA. 



1. Terebra serotina. PI. X. Fig. 20. Ter. testa lanceolato-turrita, basi breviter recurva, anfrac- 

 tibus planulatis, superne plicato-nodulosis, deinde arcuatim liratis, litis striis transversis numerosis irregu- 

 laribus decussatis; citrino-aurantia. 



Hab. Japan Island, Nangasaki Bay. 



The noduled sculpture round the edge of the whorls, forming somewhat of a shelf, 

 makes the sutures very distinct. The nodules are slightly plicate and pass into arched 

 concentric ridges. 



2. Terebra albicostata. PL X. Fig. 5J1. Ter. testa subulata, anfractibus superne plicato-nodosis, 

 deinde costatis, costis angustis, subirregularibus, interstitiis transversim impresso-striatis ; castaneo -rufa, 

 costis nodisque albidis, anfractu ultimo basin versus albifasciato. 



Hab. China Sea. 



The ribs and nodules, although naturally white, appear colourless from the effect of 

 abrasion. 



3. Terebra celata. PI. X. Fig. 22. Ter. testa lanceolato-turrita, anfractibus longitudinaliter 

 arcuatim plicato-costatis, costis liris duplicatis striisque transversis cancellatis, sulco unico conspicuo infra 

 suturas; alba. 



Hab. Philippine Islands. 



The chief peculiarity of this delicately carved species consists in the transverse ridges 

 being finely duplicate. 



4. Terebra areolata. PL X. Fig. 23. Ter. testa lanceolato-turrita, gracili, anfractibus planis, 

 longitudinaliter plicato-costatis, costis tumidiusculis, confertis, subundulatis, interstitiis alveolatis ; rubella, 

 albo variegata. 



Hab. China Sea. 



The opake white marbling of the shell is mainly upon the ribs, which have a swollen 

 appearance, and are unusually close-set. 



5. Terebra roseata. PL X. Fig. 24. Ter. testa subulata, anfractibus plicato-costatis, costarum 

 interstitiis liris tenuibus clathratis, sulco prominulo infra suturas ; pallide rosea.
