Four young specimens, 3 inclies long, from Kilbrennan Sound, 
in 24 fathoms. March. 
Six adult, half-grown and young specimens, between San da 
Island and Ailsa Craig, in 24 and 30 fathoms. March 6 and 17. 
The adult specimens are almost ready to spawn, and have the 
stomachs empty, whilst the immature individuals had freely fed on 
crustaceans.

Three specimens were obtained in April, viz., in Lamlash Bay 
(6 to 18 fathoms), off Whiting Bay (20 fathoms), and off Cumbrae 
Light (56 fathoms). 
Five specimens in August, off the Cloch Lighthouse, in 43 
fathoms. 
Two adult specimens, male and female, obtained in Kilbrennan 
Sound, at an uncertain depth (10-45 fathoms), on March 22. 
These last specimens are of special interest, being a pair which 
were engaged in spawning at the time of capture, and the breeding 
dress of the male not having been previously observed. The female 
is nearly 2 inches long, and has the ordinary coloration as shown in 
the original figure {Ann. and Mag. Nat. Hist.^ 1867, xx. pi. v.). The 
male, of which I give a figure here, is only 1 J inch long, and has 
a uniformly coloured body, without any spots. The first dorsal 
fin is very high, much higher than the body, the five anterior spines 
being nearly equally prolonged, so as to produce a horizontal upper 
outline of the fin ; only their points project beyond the membrane. 
The pectoral, anterior dorsal, ventral, and anal fins are blackish, 
and the caudal fin uniform white. The second dorsal is very 
beautifully ornamented, the lower half being of a blackish colour.
