PALINURUS. 
PALINURUS. Daldorf, Fabricii, Lamarck, Latreilie, Bosc, Leach. 
Antenne interiorcs breviores, setis duabus articulatis; exteriore breviore, compressa inferné 
dilatata, pedunculus longissimus 3-articulatus ; articulis, primo longiore, secundobreviore : 
Exteriores setacee longissime, articulis tribus basilaribus crassissimis, spinosis ; 
articulis aliis brevissimis fasiculato-pilosis. 
Palpi pediformes articulis sex exsertis, ultimo acuminato, subobtuso, hispido. 
Ocwi pedunculo communi transverso. 
Pedes decem; par anticum crassius, subdidactylum indice abbreviato ; pollice interné fasciculato- 
piloso; paria secundum, tertium, quartum et quintum simplicia, nuda; wngues fasciculato- 
pilosi, apice curvati nudi. 
Abdomen 6-articulatum, segmentis lateribus spinoso-productis. 
Cauda pentaphylla; lamellis membranaceis processu medio elongato-subquadrato apice rotundato, 
basi crustaceo ; processibus aliis squama crustacea ad basin externé, 
Interior antenne shortest, with two articulated sete; the exterior seta compressed and 
dilated beneath ; peduncle very long, triarticulated, the first joint longest, the second shortest ; 
exterior antenna setaceous, very long, the three first joints very thick, spiny; the other joints 
very short, with fasciculi of hairs. Feet-like Palpi with six exserted joints ; the last acuminate 
sub-obtuse, hairy. Eyes with a common transverse peduncle. Leg's ten; anterior pair thickest, 
subdidactyle, the finger abbreviated, the thumb internally with tufts of hair. Other legs simple, 
naked; claws with tufts of hair, their points naked and bent. Abdomen six-jointed, the sides of 
the segments produced into spines. Tail composed of five membranous lamellz, the middle of 
which is elongate-subquadrate, with its base crustaceous; the others with a crustaceous scale 
at their base externally. 
Aristotle, Athenzus, and Pliny were acquainted with the animals of this genus, which they 
named «agafos and Locusta, and used them as food. 
The Palinuri live on fish and on other marine animals; they have the power of producing 
a very loud noise by rubbing the first joint of their exterior antenne against the projecting clypeus. 
All the species have a large spine over each eye, and from this part some of the subsidiary 
specific characters may be drawn.
