OFF THE SOUTH-WEST COAST OF IRELAND. 311 



D. 10/52. A. 50. 



Lengtli of the head somewhat less than one quarter the total 

 length of the body, excluding the caudal fin. Eye equal in length 

 to the snout. Length of eye rather more than one third the length 

 of the head. Interorbital space less than the height of the eye. 

 Barbel about three quarters the length of the eye. The first dorsal 

 has its origin behind the insei'tion of the pectoral fin. The third 

 ray of the first dorsal is the longest, but is not as long as the head. 

 Length of the pectoral less than that of the head. Ventrals extend 

 as far back as the third or fourth ray of the anal fin. Vertical and 

 caudal fins edged with black. 



The specimens described are 20 cm. long. 



Haloporphyeus eques, Gunth. 



One specimen was obtained at Station 2, 400 fath. New to 

 Great Britain. Numerous specimens were obtained in the Faroe 

 Channel by the " Knight Errant" in 1880 and 1882. 



Maceueus cceloehynchus, Risso. 



Three specimens from Station 1, 200 fath. This species and the 

 followinor were unknown to British fauna before Mr. Green's ex- 

 pedition. 



Maceueus l^vis, Lowe. 



Several specimens from Stations 1 and 4. 



Rhombus boscii, Risso. 



Many specimens from Stations 1, 4, and 7. I at first mistook 

 this species for the " megrim," Rhombus megastoma, but the enor- 

 mous size of the eyes shows it to be R. hoscii. At Station 1 we 

 trawled nearly a hundred, and ate nearly all of them under the impres- 

 sion that they were megrims. They are very good eating. This, again, 

 is a species found by Mr. Green, and previously new to British fauna. 



Aenoglossus lateena, Giinth. 



Many small specimens from Stations 5 and 7, 70 fath. 



Pleueonectes cynoglossus, Linn. 



Stations 1 (200 fath.) and 8 (70 fath.).
