 A single individual only of this most curious and interesting little 

 fish has yet appeared. It forms a most distinct genus, throwing 

 considerable light on the affinities of several other genera, which, 

 before its discovery, had been placed very much at random.

I procured three or four examples of this species by dragging with 

 a net at the mouth of the Machico river. They were all caught in 

 perfectly fresh water, in a place which was quite cut off from all 

 communication with the sea, except in the time of winter-floods or 

 particularly high tides. The species was quite unknown to the 

 fishermen.

The usual exposure of the ends of the maxillary in the Madeiran 

 fish prevented an earlier recognition of its proper name and synonym. 

 They are only occasionally, and, except in full-sized fishes, rarely, — 

 not generally or characteristically, as must be inferred from MM. 

 Cuvier and Valenciennes' account of the species, — " entierement 

 caches," although their figure represents them more correctly par- 

 tially exposed.

Blennius parvicornis of my Suppl. (Proceed. 1839, p. 83 ; Trans, 

 iii. p. 9), but not of MM. Cuvier and Valenciennes, proves to be a 

 mere variety, or perhaps monstrous state, with a notched dorsal fin, 

 of the common Bl. palmicornis, Cuv. and Val. It is Bl. palmicornis, 

 var. y strigata, nob. Another var. (p sinuata, nob.) of the same 

 species has the dorsal fin merely faintly sinuate, instead of notched 

 like var. y, in the middle. As for the true Bl. parvicornis of Cuvier 

 and Valenciennes, which, having the dorsal fin even*, cannot be re-
