RHYTIDA. 119 



R. TESTUDINARIA, Gassies. PL '24, fig. 66. 



Turbinately depressed, moderately solid, obliquely rugosely 

 striate, with impressed spiral lines, more visible on the periphery 

 and subplanate base ; shining, yellowish olivaceous, with a 

 superior dark chestnut band ; last whorl flattened obliquely at 

 the aperture; aperture bluish white, showing the band, with a 

 basal lamella and slight exterior pit. Diam. 13, alt. 7 mill. 



New Caledonia. 



Was described from juvenile specimens. R. Pauluccias, Crosse, 

 which I have figured, is the adult. Is E. Coguiensis, Crosse, a 

 variety of this species ? 



R. BRUNIANA, Gassies. PI. 28, figs. 37, 38. 



Rather thin, shining, striulate; yellowish brown, with chestnut 

 maculations at the suture, and chestnut oblique, flexuous lines 

 over the rest of the shell, becoming indistinct on the base ; last 

 whorl subangulated on the periphery, slightly scrobiculate at 

 the base, corresponding with a lamella at the base of the aper- 

 ture ; umbilicus narrowly perforate. Diam. 9, alt. 3 mill. 



New Caledonia. 

 R. TURNERI, Pfr. 



An unfigured species, with nearl}* closed umbilicus, depressed, 

 snbdiscoidal, rather thin, diaphanous, a little shining, closely 

 striate; yellowish brown, variegated with chestnut lines and 

 spots, and maculated at the rather deep, denticulated suture ; 

 aperture with a median basal lamella. Diam. 7'25, alt. 3 mill. 



New Caledonia. 



The description appears to agree pretty well with R. 

 Bruniana.

Subcarinate, strongly striated, shining; brownish yellow 

 undulately strigate with chestnut; suture linear, subplicate ;

 R. Boydii, Angas (figs. 43, 44), is a synonym.
