Extracts from the Minute-Book of the Linnean Society. 587 
shot a Greater Pettychaps, the legs of which were tinged 
with flesh-colour ; and if Linnæus described from such 
a specimen when stuffed and dried, he would unques- 
tionably describe the legs as dark brown or fuscous. 
Mr. Sheppard upon the whole is satisfied that ** the 
Greater Pettychaps is the Motacilla Hippolais of Lin- 
næus, or Sylvia Hippolais of modern authors ;" and 
he proposes that the Lesser Pettychaps or Lesser Willow- 
Wren should be named ** Sylvia achetella, from its every 
now and then, while the female is sitting, shivering its 
wings, and finishing its song with a cry very similar to 
the noise made by some species of crickets.” 
The following Observations by the Rev. Revett 
Sheppard were also read, viz. i 
** Esox lucius. No author that I know of has noticed 
the migration of Pikes, such as takes place yearly in 
spring in the Cam, up which river they come in great 
shoals, doubtless from the fens in the neighbourhood 
of Ely, where they are bred. 
** Cyprinus Brama. There exist in the river Trent, 
in the neighbourhood of Newark, two species or va- 
rieties of Bream. The common one, Cyprinus Brama, 
is known there by the name of Carp Bream, from its 
yellow colour, and has been taken of nearly 8lbs. 
weight. The other species or variety, which I believe 
to be nondescript, never exceeds a pound in weight. 
It is of a silvery hue, and goes by the name of White 
Bream. 
* Talpa europea. A variety of the Mole is occa- 
sionally found at Levington, in the county of Suffolk. 
The snout is white, and a white line extends from the 
middle
