Onus maculatus. Greater Three-Bearded Eockling. 
Of the two species of three-bearded Eockling which are found on 
the British coasts, this is the larger species, attaining to a length of 
18 inches. It is the species which I have described in the Cata- 
logue of Fishes as Motella maculata ; whether or not it is identical 
with Eisso’s Onos maculata I am unable to decide from insufficient 
materials of the Mediterranean forms, but it is the. Motella vulgaris 
of Ltitken. I cannot consider the large size of its front teeth to be 
a sign of age, having compared specimens of Onus tricirratus of 
the same or even larger size of body, which lack the large teeth 
altogether. The pectoral fins of the British specimens of Onus 
maculatus have twenty-two rays, and the ventrals eight. 
A specimen, inches long, was obtained in Loch Fyne, in 40
