it was discovered, and in compliment to whom we name it Mon'

Mr. Montagu has seen three or four specimens of tliis fish on the 
Devonshire coast, two of which he found lately near the ThurlstonC 
rock, on the South coast of Devonshire. This diminutive species is 
about three-fourths of an inch in length : perfectly smooth ; of 3 
pale colour, tinged with pink, and marked all over the upper parts 
and sides with numerous distinct roundish spots of purplish brown- 
The head is large, and rather inflated about the gills, contracting 3 
little in front: the body decreases gradually as far as the vent, and 
afterwards still more considerably quite to the tail. The mouth is not 
large in proportion to the size of the fish : its hides are silvery, with the 
pupil black : gill covers obscure. It has no visible lateral line. The 
pectoral fins consist of seventeen or eighteen rays ; these are placed 
just before the sucker or instrument of adhesion, and turn under- 
neath : the ventral fins nearly unite at their base, partly surround 
the sucker, and are so approximate to the pectoral fins as to appear 
connected : the anal fin is formed of about thirty rays, commencing 
immediately behind the vent : the dorsal fin originates a little nearer 
towards the head*, but many of the first rays are imperceptible 
without the assistance of a deep lens ; those which are conspicuous 
amount to about sixteen or eighteen, and both the anal and dorsal

instance has been kindly corrected since the plate was published. Mr. Montagu ha^ 
delineated and described the dorsal fin as originating lower towards the tail than >' ie 
anal fill ; but soon after discovering another specimen, he perceived that he had bef« re 
entirely overlooked the anterior part of the dorsal fin, which consists, as above mention® 1 *' 
of a number of almost imperceptible rays, connected to the series of conspicuous ray*
