STROMBUS. 267 
on both the second and third horizontal rows, but, as no 
numerals were attached to the drawing, Linnezus has altogether 
avoided citing that plate. 
Strombus scorpus., 
Both the Pterocera scorpio and Pt. pseudoscorpio are marked 
for this shell in the Linnean cabinet, but as the name can only 
be retained for one of them (Reeve has suggested that the 
latter may prove only a local variety of the former), it is 
desirable to follow tradition, especially as both Rumphius and 
Argenyille (to which reference Linnzus has added “bona” in 
his own copy) decidedly represent it, whilst the engraving of 
Gualtier, even if designed for pseudoscorpio, was taken from an 
uncharacteristic young example. The locality, moreover, suits 
the former (Sow. Thes. Conch. vol. i. Pter. f. 1). The descrip- 
tion in the ‘Museum Ulrice’ is very ample. 
Stronbus lambdts. 
The Pterocera lambis (Sow. Thes. Conch. vol. i. Pter. f. 5) of 
authors is marked for this shell in the Linnean collection. 
The synonymy upon the whole is good: the reference to 
Bonanni, however, must be expelled, it would have been more 
appropriate for chiragra. Lister, plate 866, figure 21, is 
referred to in the revised copy, and “bona” appended to the 
reference (misprinted F in the Vienna edition) to Argenville. 
The account of the claws in the ‘Museum Ulrice’ reminds one 
more of P. bryonia than of ordinary specimens of lambis. 
Strombus millepedsa. 
The Pterocera millepeda (Sow. Thes. Conch. vol. i. Pter. f. 3) 
of authors is marked for this shell in the Linnean cabinet, and 
agrees with its descriptions and the cited delineations of Rum- 
phius, Bonanni, and Lister, plate 869 (copied from the Italian 
publication). Argenville, too, represents an immature example,
