TelUna. V. Berlin gives a revision of this genus, chiefly from the 
material in the Paris Museum. He discusses first the geographical distri- 
bution, giving lists of the species known from the different seas, as Medi- 
terranean, W. Indies, &c. [the two indicated for Magellan Straits, T. 
virgata and dispar ^ appear to the Recorder very doubtful]. Systemati- 
cally, he adopts the following genera and subgenera : — TelUna (L., 
restricted), with subgg. Tellinella (Gray) 60 sp., Peronceoderma (Poli), 
9 sp., Pseudarcopagia (n.) 2 sp., Quadrans (Klein) 3 sp., Donacilla (Gray) 
9 sp., Fahulina (Gray) 29 sp., Peroncea (Poli) 13 sp., Tellinides (Lam.) 
6 sp., and Homala (Morch.) 2 sp. ; also the genera Strigilla (Turt.) 8 sp., 
Arcopagia (Leach) 17 sp., TelUdora (Morch) 1 sp., Phylloda (Schum.) 
1 sp.. Metis (H. Sc A. Ad.) 6 sp., Macoma (Leach) 34 sp., and Gastrana 
(Schum.) 7 sp. The number indicates the number of species represented 
in the Paris Museum and examined by the author ; many of them are 
accompanied by critical notes and indications of new localities. 148 other 
spp. of the restricted genus TelUna and 119 of other genera only known 
to the author from descriptions, are enumerated. N. Arch. Mus. (2) i.
