from the Coast of Ireland. 403 



Future paper. To my friend Dr. Scouler, Geological Professor 

 to the Dublin Society, I am indebted for many valuable notes 

 on the habits, &c, of the various species now treated of, as 

 well as for his kindness and polite attention whenever I 

 wished to examine any of the specimens under his care. 



Trigla Blochii. This is a rare fish with us, but several spe- 

 cimens have been brought to me from Kingstown, Dublin. 



Coitus Grcenlandicus (Richardson's Fauna, Br. Ann. p. 297, 

 pi. 95, fig. 2). A fine specimen of this fish, nearly 10 inches 

 long, is in the collection of the Royal Dublin Society, from 

 Kingstown, near Dublin ; two other specimens were taken 

 during the last week in the bay, and are now in my posses- 

 sion ; and last evening I procured a beautiful specimen near 

 the mouth of the river Liffey, which is also in my collection. 

 I believe this fish is new to the European Fauna. 



Thynnus Pelamys, Bonito. A splendid specimen of this rare 

 fish, taken off the coast of Dublin, is now in the collection of 

 the Royal Dublin Society. 



Mugil Chelo and Mugil Capito have occurred to me in nearly 

 equal abundance at some periods of the year in Dublin bay, 

 These species are very nearly allied. Specimens of both are 

 in the Museum of the Royal Dublin Society. 



Gobius fuliginosus (M'Coy). 



Length 2 inches, depth 4 lines. Dorsals continuous : rays very 

 long, second and third longest ; first ray half a line shorter than the 

 second ; third ray 3| lines in length in the second dorsal ; third and 

 fourth rather the longest in the first dorsal ; pectoral, when laid flat 

 against the side, reaches to opposite the third ray of the second dor- 

 sal ; from the anterior base of the ventral fins to the vent, 6 lines ; 

 from the same point to the apex of the ventral fin, 3 \ lines : eyes 

 moderate, half their diameter apart. Lower jaw longest ; the gape, 

 when the mouth is shut, extending obliquely upwards from the ex- 

 ternal angle : forehead and nape convex, no sulcus ; beneath white, 

 sides and back dusky ; a few obscure spots on the lateral line : ven- 

 tral fin white, the rest dusky with blackish margins ; snout and 

 space between the eyes blackish, and a few blackish spots on the 

 chin (in spirits). 



D. 6. 16; C. 17; A. 13; P. 20; V. 9. 



The posterior rays of the anal fin longest, last somewhat shorter. 



The only specimen I have seen was from Connamara, 

 taken in company with G. niger. 



Gobius reticulatus. Two specimens of this most beautiful 

 Goby were taken by dredging in shallow water in Dublin bay.
