adopted name will be Dunkeri, which has decided priority of 
publication.” Also “7. Taylorianus, Rve., appears to be a worn 
immature state of J. cinereus, Rve.,” loc. cit. The worn state of 
Jonas’s specimen is not so evident tome. It is certainly the 
same shell as Siphonalia fuscozonata, Angas (Proc. Zool. Soc., 
1865, p. 56), which from Jonas’s priority of definition becomes a 
Synonym. It is nota Siphonalia, but a Fusus, as is plain from 
its dentition given in pl. iii, fig. 6. In Mr. Adcock’s list it is 
classed as a Peristernia, but it has no trace of columellar folds.

Tryon says (Man. of Conch., vol. IIT., p. 66), “ The coloration 
and very short canal remove this species from /rsus, yet I do 
not know where to locate it. Resembles a Muricidea.” Its 
dentition I have shown on pl. iii, fig. 7. There is a rachidian 
tooth with three small cusps, and long curved saw-like laterals. 
The prongs of these are very variable in size, not only on any 
particular lateral, but even corresponding prongs on any pair of 
laterals, or on consecutive laterals. The radula disposes at once 
of any suggestion to place it among the uricide as a Muricidea 
or Ocinebra, and classes it with the Muside ; while the absence 
of columellar folds decides its position in the genus /usus. How- 
ever, unlike ordinary species of the genus, it is left there by a 
process of exclusion.

The habitat is given there as “The shores of New Holland,” 
with the added note, “A species which still appears rare in col- 
lections. We do not know the locality. ‘The Museum (i.¢., the 
Paris Natural History Museum) has two individuals.” The 
shell which has hitherto been considered as F. fusiformis among 
local collectors is only a comparatively smooth variety of 
F. coronata. The true species is rare here, and is represented by
