PARTULA, NEW HEBRIDES. 281 



compared it with a Cumingian specimen of macgillivrayi 

 in the Newcomb collection (see Nautilus XI, 1897, p. 44). 

 According to the measurements given by Pfeiffer, macgil- 

 livrayi has a larger aperture. The unique type of P. eximia 

 is figured and described.

"Shell dextral, ovate, very elongate, solid. Spire half the 

 length ; whorls 5%, oblique striae coarse, spiral striae obsolete, 

 aperture a wide oval, more or less oblique; umbilicus com- 

 pressed. Columella wide above, lip reflected, white and flat, 

 margins of the peritreme connected by callus. Color ivory- 

 white. In fresh examples sometimes the whole shell is tinged 

 with pale rose. Length 26, diameter 13, length of aperture 

 11, diameter 6 mm." (Hartman). 



Habitat unknown.

"Captain Brazier sent me two examples of this shell, given 

 him by a friend; it is larger and more solid than pfeifferi 

 Crosse." (Hartm.) 



Dr. Hartman 's description is given above and a photograph 

 of his type is copied. The type and another example were 

 returned to Mr. John Brazier of Sydney, N. S. Wales. On 

 the photograph of eburnea presented to the Academy Dr. 

 Hartman marked ' ' = macgillivrayi Pf r. ' ' 



70. P. PYRAMIS Hartman. PI. 33, fig. 7. 



The shell is deeply rimate-umbilicate, rather thin, ovate- 

 pyramidal, -white under a very thin whitish cuticle which is 

 indistinctly marked with narrow yellowish- green streaks on 

 the last whorl. Spire slender, long. Embryonic whorls conic 

 and but slightly convex, much as in P. brazieri. Subsequent 

 whorls convex, the penultimate and last whorls very strongly 

 convex. The later part of the last whorl is flattened laterally ; 

 base very full, sack-like. Spiral lines well spaced on the 

 penultimate whorl, wanting on the last except at the base.
