general form quite dissimilar. Elusa is turriculate, and attenuately 

 fusiform ; Mormula, rissoid, and scarcely plicate, though like Herviera 

 in solidarity, and to some extent, in the longitudinal costae. From 

 any of the Odostomice, inclusive of Pyrgulina, Parthenia, Chrysallida, 

 Mumiola, etc., it amply differs in the characteristic thickened sub- 

 stance of the shell, in coloration, in the absence of any decussating 

 striae, in continuous peristome, and peculiar columellar plait, though 

 in general form it resembles certain Pyrgulince. 



We have much pleasure in being able to dedicate this genus to one 

 who is so successfully investigating the molluscan fauna of the 

 Loyalty Islands, and is publishing from time to time in the pages of 

 the Journal de Conchyliologie admirable descriptions, which have been 

 and are of such signal service to us, the Abbe Joseph Hervier, S.J. of 

 St. Etienne, Loire, France. 



The second species of the genus is now to be described as follows : — 

 Herviera isidella sp. nov. 



H. testa oblongo-fusiformi, viultum attenuata, pallide puniceo-brunnea, 

 solidiusciila, Iczvi, nitida ; anfractibus septem, apicali incluso per- 

 vilreo, pellucido, dorsaliter heterostropho et retorto ; apud suturas 

 impressis, ventricosulis, undique iongitudinaliter arete reetieostatis ; 

 costis, 7it in typo ( H. gliriella) perlcevibus, nitidis, interstitialiter 

 leevissimis ; apertura parva, ovata ; peristomate paulhwi incrassato, 

 conlinuo ; columella uniplicata, plica obliqua. Long., 3 mm. ; 

 Lat., 1 mm. 

 Hab. : Uvea, Loyalty Islands, New Caledonia. 



Two examples of a species much resembling the type 

 in substance and general characteristics of sculpture, but 

 of far more graceful form, being attenuate, oblong fusi- 

 form, of a pale pinky brown hue, somewhat solid, 

 smooth, shining. Inclusive of the bulbous, pellucid, 

 smooth glassy-brown apical whorl, dorsally retrorse, 

 the whorls are seven in number, and are suturally im- 

 pressed, somewhat tumid, and uniformly straightly ribbed, Herviera 

 the costse being rather thick, smooth, and close, the isidella, x 8. 

 interstices likewise smooth. The aperture is some- 

 what small, ovate ; peristome thickish, continuous ; columella once 

 plaited ; plait oblique, but not so pronounced as is that of the 

 typical species. 



The likeness, in miniature, of the whorls to the longitudinally ribbed 

 jointed sections of the well known Alcyonarian {Is is hippuris L.) sug- 

 gested the trivial name.
