preesertim) attenuatum. 
SEALEECH. 
GENERIC CHARACTER. 
Body slightly contractile, oblong, round, both extremities, 
(especially the anterior extremity) attenuated. 
This genus is figured by Rondeletius, who in his de- 
scription seems to have confounded it with the genus dre- 
nicola. 
The species have been confounded with each other, un- 
der the titles hirudo muricata, p. piscitum, and sea-leech. 
Linné has referred to two figures for his hirudo muricata, 
one of which, in the “ Museum Fridrici Adolphi,” exhi- 
bits two hooks proceeding from the mouth of the animal, 
(and this figure has been copied inio Pennant’s British 
Zoology and Rees’ Cyclopedia) ; the other figure in Bas- 
ter’s Opuscula Subseciva*, leaves no doubt as to the genus 
intended.
