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, ina 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,—‘‘ entiérement 
cachés,”’ although their figure represents them more correctly par- 
tially exposed.

Blennius parvicornis of my Suppl. (Proceed. 1839, p. 83 ; Trans. 
iil. 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. ((3 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- 
ferred correctly to either of these states of the species, I feel autho- 
rized, after examination of perhaps some hundred individuals of this 
common little fish, with a particular view towards the confirmation 
of the form in question as a species, to pronounce it a mere trivial 
and accidental aberration (so far at least as concerns the Madeiran 
* “ Sa dorsale est continue.”’ Cuy. et Val. xi. 258.
