214 THE FAUNA OF THE SALCOMBE ESTUAltY. 



approached. It was abundant in dredgings from the channel in the 

 Kingsbridge estuary, especially immediately west of the Salstone. 



DiDEMNiDS. Specimens were dredged in the channel west of the 

 Salstone, and also obtained on the western shore of the same island, 



PISCES.* 



[Nomenclature : Day, British Fishes. ] 



COTTUS, sp. A specimen is recorded by Mr. Todd from the zostera 

 south of Pilworthy Point. The specimen was not kept, so that the 

 species is uncertain. Several were also obtained under the Marine Hotel. 



GoBius PAGANELLUS, Gmel. Linn. Taken in zostera under the 

 Marine Hotel and on the eastern side of Kingsbridge estuary. 



Gobi us euthensparri, Eiqihr. Abundant in the zostera and along 

 the shore at all points (under the Marine Hotel, Snape's Point, mouth 

 of Southpool Lake, Salstone). 



Goby larv?e, from 2*5 to 5*5 mm. in length, probably referable to 

 this species, were taken abundantly in tow- nets between Snape's Point 

 and Ditch End, August 7th to 12th. 



Aphia pellucida, Nardo. One young specimen, 12 mm. in length, 

 was taken in zostera under the Marine Hotel on July 14th. It 

 resembles the adult female in general features, but is slightly more 

 slender in form and still scaleless. For observations on the habits 

 of this species in Plymouth Sound see this Journal, v. pp. 89 and 338. 



Centronotus gunnellus {Linn.). Mr. Todd found one specimen on 

 the south end of the Salstone, in an empty Buccimtm shell. 



Callionymus LYRA, Liuji. A young specimen, 12 mm. long, was 

 taken on the zostera bed opposite Snape's Point on June 16th. 



Labrus maculatus, Bl. Four young specimens were taken in zostera 

 under the Marine Hotel on July 14th. Three are about one inch in 

 length (23 to 28 mm.) ; the fourth is much smaller, measuring only 

 11*3 mm. Even at this stage the species is readily distinguishable 

 from its congeners by the fin-ray formula of the dorsal and anal fins, 

 which for all four specimens was as follows : — 



D. XX.— XXI; 10-11. A. Ill; 9-10. 



The last two soft rays of each fin have been counted as one, in 

 accordance with Giinther's method. From C. melops of the same size 

 the youngest specimen is also distinguishable by the uniform distribution 

 of the chromatophores on the sides of its body, as far back as the 

 hinder margin of the dorsal and anal fins, where they cease (cf. Ct. 

 rupestris, Holt, Ann. Mus. Marseille, v., 1899, pi. 5, fig. 49). 



Crenilabrus melops, Lin7i. Very young specimens, from 7"7 to 

 11 "5 mm. in length, were taken in large numbers in the zostera under
