placed in the genus Pleurofoma ; that it is the Fusus costu- 
fatus of Cantraine, but as the type of the latter has been 
lost he adhered to his specific name haliaéte. 
Although Cantraine’s species was for a time identified 
with C. haliaétz, it is now held to be the same as Philippi’s 
Buccinum acuticostatum, a Calabrian pliocene fossil, which 
is certainly not Jeffreys’ C. Aaliaété according to Boog 
Watson. | 
_ The conclusions of Seguenza and of Monterosato 
cannot be accepted on this point, as the species they had 
before them was Buccinum acuticostatune Phil. 
Then, as to Hornes’ Columbella corrugata (which he 
referred to Buccinum corrugatum Broc. whereas the latter is 
a /Vassa), his species is provided ‘with strong teeth’ both 
on the inner and outer lip, which is not the case with C 
haliaétz; teeth are present but they cannot be called strong. 
But if Hornes’ C. covrugata is the same thing as ours, then 
Michelotti’s name of arpula is prior. Dr. Watson well 
says—‘It is obvious that there is here a whole group of 
Columbellas greatly in need of revision.’ 
However, it is so far clear up to the present that C. 
haliaéti of Jeffreys has as much right to stand as a species 
under that name as under any other. 
Mr. Sowerby figures this in his Index as a smooth 
white shell; but it is strongly ribbed, with interstitial 
strie, and of a light yellowish brown. 
Cylichna umbilicata var. conulus S. Wood gives place to 
S i 
C. ovata Jeff.. (See J. of C., vol. vii., No. 8). 
Scaphander librarius Lovén was described and published 
five years subsequent to Bulla punctostriatus Migh. and Ad., 
so that the latter specific name takes precedence. 
Spirialis retroversus Fleming. Zzmacina was published 
long prior to Sfzvva/ts, and is now generally used. 
S. retroversus var. jeffreysi F. and H. This variety should 
be cancelled. It is admittedly immature. I have some
