Pale, coloured with flesh-red, spotted with black-purple ; 
the anterior margin of the sac, the under surface of the fins, 
and the inner aspect of the feet, pale saffron or luteous. 
Length from the base of the legs to the extremity of the 
sac one inch. 
This species, which appears to have been unknown to the 
ancients, who probably confounded it with the young of Sepia, 
was first noticed and described as a genus by that excellent 
observer of nature, Rondeletius, who has accurately pointed 
out the essential characters which divide it from Sepza and Lo- 
igo; I have consequently named this, the only known species, 
after him. 
Inhabits the bottom of the sea amongst gravel, and in estu- 
aries, where it is often taken along with oysters. It is not un- 
common at Plymouth, in the Kingsbridge Estuary at Saleombe, 
and at the mouth of the Thames. Pennant received it from the 
Flintshire coast.
