the eggs have hatched, and the animal has grown to maturity by 
the first of November. With Helix alternata the growth was much 
less, hardly making more than one-half that of H. appressa.— Chas.

ARGONAUTA ARGO on the East Florida coast.—A specimen of 
this species measuring 7% inches diameter, and perfect in every re- 
spect, has been obtained by Mr. Wm. P. Stanley. It was found 
about 10 miles below Palm Beach, and contained the animal when 
cast ashore. 
RECENT PUBLICATIONS. 
Oxpras MaALaAcoLoaicas DE J. G. Hipateo. Madrid, 1894. 
The name of Joaquin GonzALez Hiparco has long been a fam- 
iliar one to conchologists acquainted with recent French and Spanish 
literature of mollusea; and whoever has used the more extended 
works “ Moluscos Marinos de Espana, Portugal y las Baleares” and 
the “ Moluscos Terrestres,’—works indispensable in the study of the 
shells of Southwestern Europe—will hear with pleasure of the pub- 
lication of the “Obras Malacologicas.” This magnum opus, of which 
several parts lie before us, will consist of three portions: works re- 
lating to the fauna of Spain, works upon the South American fauna 
and publications on the land shells of the Philippine Islands. Of 
the former two we may judge in advance by the magnificently illus- 
trated volumes named above, and the “ Moluscos del Viaje al 
Pacifico.” 
That upon the Philippine fauna, now in course of publication, aims 
to present asummary of the literature of each species, with valuable 
critical notes on the variations, distribution, ete.; and it is illus- 
trated ona scale which leaves little to be desired. The land snails 
of the Philippines are among the most beautiful of any region, and 
it is only fair to say that for the first time justice is done them in the 
splendid plates of Hidalgo’s Obras. The Helices and Cochlostylas 
are illustrated in the parts already issued, and we hope to have the 
Bulimi and operculates before long. The text is characterized by its 
moderate and conservative spirit, refreshingly free from “ nouvelle 
ecole” vagaries, but well abreast of the times.
