THE NAUTILUS. 103 



clear ferruginous bauds, one a short distance below the 

 suture, the other just above the keel. These bands are inter- 

 rupted by irregular white opaque flecks at frequent intervals. 

 The shell is much thinner and more sharply keeled than L. 

 chrysomela. The species is considered to be extinct, but the 

 finding of such fresh specimens suggests that it may yet be 

 found alive. 



L. chrysomela var. bifasciata n. var. Max. diam. 11 mm., 

 with the usual solid form and orange mouth. Two very broad 

 (diam. about 1.5 mm.) grey bands, necked with white, one 

 above, the other below the periphery. The bands have a faint 

 reddish tint, and were doubtless dark or red in life. Fossil 

 in Porto Santo. The typical form is chalky white, unbauded. 



Leptaxis exornata (Deshayes). This seems to be the proper 

 name for L. erubescens, Lowe's name being invalidated by 

 H. erubescens Solander, Portland Cat,, 1786, as Mr. Tomliii 

 kindly pointed out to me. The description of exornata agrees 

 exactly, except that the pale band between the dark ones is 

 not really white, with a small elevated form of erubescens 

 found in Madeira. My specimens are from the Pico do In- 

 fante, collected by the Rev. Drummond Paterson. H. simia 

 Ferussac is also apparently erubescens, but if so, the figure is 

 extremely bad, and Pfeiffer in Conchylien Cabinet remarks 

 that he might have thought it a variety of H. splendida had 

 not Beck declared it to be from Madeira. Pfeiffer had not 

 seen the shell, but described it from Ferussac 's figures. The 

 shell is rather unusually depressed for erubescens. 



Leptaxis furva var. grandissima n. var. Shell very large, 

 almost 26 mm. max. diameter; last whorl swollen and aper- 

 ture large; one band in the usual position, but the shell is 

 white and the band is colored as in the specimen of fluctuosa 

 described above. In the R. McAndrews collection at the Uni- 

 versity of Cambridge. The label gives only Madeira as the 

 locality, but the specimen is probably a fossil from Canigal, 



Leptaxis forensis (Wollaston). This is certainly very close 

 to L. wolla-stoni Lowe, and if considered only a variety, it 

 must take the name L. ivollastoni var. minor (Paiva), which 

 has priority.
