FROM TALIABU. 125 



very flat specimens occur, I see no reason to separate them 

 even as a variety. 



8. Crystallopsis ohliquata Desh. 



Desh. in Ferussac, Hist. nat. des Moll. I, p. 219, 



PL 28 A, figs. 3 et 4. 



Under this name I include two specimens, which differ 

 slightly ; the youngest of the two agrees in most respects 

 with Ferussac's description and figure, but the upper margin 

 of the aperture descends not so much, consequently the 

 aperture is a little higher; in the dorsal view I can see 

 no difference of any importance; in the other specimen 

 the aperture descends still less and the last whorl is less 

 laterally compressed. As however these characters prove to 

 be variable in these respects, I don't doubt that they must 

 be referred to Ferussac's species. Under the lens 1 observe 

 very fine spiral striae; especially the younger shell has a 

 slight yellowish tinge. The habitat of the species was still 

 unknown, for specimens recorded from Tormio, Tukan-besi, 

 differ considerably from Ferussac's figure, and belong, ac- 

 cording to Prof. 0. Boettger, to C. phy sails Pfr. 



9. Auricula Judae Lin. 



Martens, Suss- u. Brackw.-Moll. p. 154, PI. VIII, 



figs. 6—11. 



One shell from the Lagoon near Lekitobi on Taliabu 

 is rather small, having only a length of 31 Mill. ; it belongs 

 to a form with short spire. It has been collected with a 

 few young specimens which belong to the Cerithidae.
