move, apparently, l)eing firmly wedged in; two others were found 

 free, on coral. 



Two specimens sent are figured. It is the narrower one which 

 agrees with Souverbie's description and figure. It measures, length 

 7.8, diam. 3.7 mm. The wider one measures, length 7, diam. 3.9 

 mm. With so small a numl:)er, one can hardly tell whether the 

 difference is merely individual variation or of specific significance. 

 Temporarily the wide variety may be called form latior (fig. 10&). 



S. apiculatum was described from a single example from Mauritius, 

 not from New Caledonia, as Tryon stated {Man. Conch. VIII, 

 p. 287). 



The apical whorl,s of this shell are like those of Stylifer, and unlike 

 .Scalenostoma. It may be taken as type of a new section distinguished 

 by the smooth attenuate early whorls, and to be called Hyperlia. 

 Whether an operculum is present has not been ascertained. It 

 appears much nearer to Mucronalia than to Melanella in characters 

 of the shell. 



Stylifer robustus Pse. is reported by Mr. Pease as living on Echini, 

 but the exact locality in the Islands was not given.

Pease was the first to determine the locality of this peculiar snail 

 tto be the "Sandwich Islands," but as usual did not note the exact 

 place. One of his shells, No. 19822 A. N. S. P., is drawn. It is 

 ibluish- white with ochraceous* markings disposed as in the figure. 

 None of the shells seen have them in such regular festoons as are 

 shown in the Thesaurus figure, which apparently served as the 

 original of Dr. Bartch's enlarged view. The spire is just perceptibly 

 ;bent in the upper part, composed of slightly convex whorls. There 

 is series of curved, linear varix-lines on both right and left sides, the 

 ilines receding a little with ascent of the spire, so that in the upper 

 part they are dorsal and ventral. The later whorls are rather con- 

 ;spicuously compressed between dorsal and ventral sides, as shown 

 in the basal outline, fig. 136, and there is a flattened area on the face, 

 near the base, banded by an acute, ascending curved angulation on 



* The specimens are beach shells, and the color has probably faded more or less.
