corneous, slightly suffused with pale fuscous. Diana, maj. 10, 

 min. 8'75 mm. ; alt. 6 mm. 



llab. — Island of Ngau. September, 1854. (MacGillivray.) Five 

 specimens. 



Type in the British Museum. 



One specimen is fuscous in colour, and measures, diam. maj. 10'5, 

 min. 9 mm. ; alt. 6 mm. 



Allied to the preceding species, but larger, the last whorl is more 

 tumid below towards the aperture, the umbilicus is narrower, the 

 aperture less dilated transversely and the angulation above the 

 periphery is much less, while the microscopic spirals of Fretum 

 lepidum are absent in the present species. 



Feetum Kichakdi, n.sp. PL XIV, Figs. \a-c. 



Shell narrowly umbilicated, depressed, conoid, pellucid, clouded at 

 the umbilical region, corneous, shining, smooth, faintly and irregularly 

 striated ; apex acute, suture shallow, margined ; whorls 5, 

 increasing rapidly, the last twice as wide as the penultimate ; 

 flattened above, rather acutely angulated above the periphery, 

 inflated below ; aperture diagonal ; margins acute, upper and outer 

 nearly straight, lower regularly curved, columeUar obliquely 

 descending, slightly reflected and overhanging the narrow umbilicus. 

 Diam. maj. 15'5, min. 13'5mm.; alt. 9 mm. 



Ilai. — Viti Levu, under dead leaves. September, 1856. (Eayner 

 and McDonald.) Two specimens. 



Allied to Fretum Hoyti, Garr., but more depressed than that 

 species and with more conical spire; the angulation of the whorls 

 is more pronounced, the whorls increase more rapidly, the aperture is 

 more dilated transversely, and the shell is of a thinner textui'e. The 

 second specimen measures, diam. maj. 14'25, min. 13 mm, ; alt. 9 mm. 



Var. atrofusca, n.var. 

 Differs from tlie type in being dark fuscous. Diam. maj. 15*5, 

 min. 13'5 mm.; alt. 9*5 mm. 



Ilah. — Suva Harbour. (Mr. Richard Ponsonby.) Two specimens. 



FiJiA Macgillivrayi, n.sp. PI. XIV, Figs. 2a-c. 



Shell narrowly umbilicated, conoid, pale corneous; spire depressed, 

 apex obtuse, suture deep ; whorls 5|, tumid, increasing slowly 

 and regularly, apical whorl almost smooth, the next regularly and 

 strongly costulate above, the costulae becoming more crowded and 

 finer on the last portion of the last whorl; costulse strongly 

 decussated by spiral sulci; last whorl angular above periphery, 

 costulse and spiral sulci descending below the periphery where they 

 terminate abruptly, below which the shell is finely striated trans- 

 versely, shining, with some distant, irregular, shallow spiral grooves; 

 aperture oblong-ovate; margins acute, regularly curved, columellar 

 shortly dilated, reflected and overhanging the moderate umbilicus. 

 Diam. maj. 12, min. 11mm.; alt. 7 mm. 



ITab. — Matuku, under dead leaves. August, 1855. (MacGillivray.) 

 Seven specimens.
