Gurnards. 



(Artedi; Linnaeus, Syst. Naturae, 1758: type, Trigia lyra L.) 



This genus differs from Prionotus chiefly in the absence of palatine 

 teeth. The scales are smaller and the pectoral fins less developed; a 

 series of bony, spinous plates extend along the base of the dorsal fins, 

 a pair of them to each ray, the fin thus running in a shallow groove; 

 caudal fin usually emarginate. Lateral line usually forking at base of 

 caudal, the branches running to tip of fin. The numerous species 

 abound on the coasts of Europe, Africa and India. [rptyXa^ classical 

 name of Mullus barbatus; transferred to this group for no evident 

 reason.) 



1122. T. cucilllis Linn. — Bed Gurnard. 



Eosered; profile of snout rather steep, slightly concave; preorbital 

 with short denticulations; maxillary nearly reaching front of orbit; 

 lateral line with a series of unarmed plates, which are deeper than 

 long; first dorsal spine tuberculated ; second longest, § length of head; 

 pectoral reaching past front of anal. Head 3J; depth 5. D. IX-18; 

 A. 17; Lat. 1. 75. Common in Europe; said by Cuvier to have been 

 once brought from l^ew York by Milbert.

(Lacdpfede, Hist. Nat. Poiss. iii, 337, 1802: type Trigia evoJans L.) 



Body subfusiform ; profile of head descending to the broad depressed 

 snout, which is much longer than the small eye; eyes close together, high 

 up; surface of head entirely bony, the bones rough with ridges and 

 granulations; scales on head few or none; preopercle with one or two 

 sharp spines at its angle; opercle with a sharp spine; nape with two 

 strong spines; a spine on shoulder girdle. Mouth rather broad; bands
