Fahrkia, Blainville (1828). Malmgren (A c. p. 117) states that this name 
having been already many times previously used in botany as a generic name, 
and besides having been used in entomology, must be rejected here. Likewise 
the name Johnston (1834), being derived from a Christian name, Otho 
(Otto), ought, both on account of its derivation and by reason of its not hav- 
ing gained general acceptance, to give way to Amphicora, Ehrenberg (183G). 
[Wo feel compelled to dissent from this reasoning, and to employ Johnston’s 
name simply on account of its priority.] 
Serpulea. ‘ 
Serpida triquetra ?. Mr. lAlder notices the following peculiarity in the 
structure of the shell of a Serqmla, possibly S. triquetra. Near the mouth there 
is an oblong bulbous swelling of the same substance as the shell, but rather 
less compact and more brittle. This terminates in a double arch in front. 
The bulbous portion consists of two cells, divided from each other by a thin 
wall of shell. The triangular tube of the body is continued through its base, 
with the mouth of the tube opening generally immediately below it. The 
species may be new ; but the animal being absent, it is not described. Brit.
