ANCILLAB.IA. 9. 65 



quadriplicate; labio externo uniplicato, infra profundi emarginato 

 (f. 46, 47). — Of an oval form, with a distinct band on the whorls, 

 typically variegated, but sometimes white. On each whorl of the 

 spire are several ridges. The spire and mouth nearly equal in 

 length. 



37. Sinensis, Sowb. Th. — A. alba, parva, A. marginata si- 

 milis, sed magis angustata, varice angustiori et magis obliqua (f. 

 50, 51). — A small white shell, resembling A. marginata, but 

 much narrower, and with the varix narrower and more obliquely 

 plicated. 



38. oblonga, Smcb. Sp. — A. ovalis, elongata, A. marginata 

 similis, sed anfractibus rectiusculis ; ultimo anfractu et balteis 

 iuferioribus variegatis ; varice parvo, triangulari ; spira laevigata, 

 pyramidali (f. 42, 43). — The shape is narrower, the aperture 

 wider at the base, the spire more pyramidal, and the varix much 

 smaller than in A. marginata, and besides, it has no ribs on the 

 spire. If, as I suppose, this is the true A. oblonga of the Sp. 

 Conch., it is more distinct from A. marginata than the fol- 

 lowing. 



39. lineata, Kien. — A. A. marginata similis, sed magis elon- 

 gata ; spira pyramidali, laevigata ; anfractu ultimo lineatim va- 

 riegato ; varice parvo (f. 57, 58). — More like A. marginata than 

 the preceding, but much narrower, with a smaller varix, and 

 without the spiral ridges. It differs from A. oblonga in not 

 having the aperture so wide at the base. 



40. Nov^-Zelandle, Sowb. TJi. — A. parva, alba, A. marginata; 

 similis, sed magis augusta ; spira laevigata, pyramidali ; apertura 

 brevi (f. 48, 49). — Like A. lineata and A. oblonga, it differs 

 from A. marginata in having no ridges on the spire ; from A. 

 lineata, which it otherwise most nearly resembles, in the short- 

 ness of the aperture. 



41. oeesa, Sowb. Th. — A. ovalis, ventricosa, pallida, fusco va- 

 riegata, medio fusco unifasciata ; spira brevi, pyramidali; anfrac- 

 tibus marginatis ; apertura magna, unidentata ; varice parvo, 

 albo (f. 44, 45). — More obese than A. oblonga, with a shorter 

 spire. The middle of the body-whorl has a broad brown band, 

 above and below which are rows of brown spots; the margination 

 is also variegated.
