length of its base is a little greater than the postorbital part of the 
head. None of its spines are much longer than the eye. 
The distance of the anal origin from the head is about § the 
length of the head. The rays of the soft dorsal and the anal are 
not much longer than the dorsal spines. 
The caudal is about § as long as the head, and its middle rays 
are somewhat the longest. 
The colour in spirits is a pale yellowish brown. The sides show 
traces of several small pale blotches, and the caudal and pectoral 
have a few very small dark blotches, those on the caudal forming 
interrupted bands. Across the back are faint indications of about 
five pale cross bands. 
The species is dedicated to Dr. Theodore Gill, in appreciation of 
his researches upon the mail-cheeked fishes. 
Three individuals have been taken as the types of the species. 
The largest is 46 and the smallest 38 millimetres in length. —

Model of the “ British Marine Area.” 
By the Rev. Canon Norman, M.A., D.C.L., E.R.S., &c. 
Since writing my notes on the “ British Marine Area,” which 
appeared in the ‘ Annals ’ for May (pp. 345-353), I have learned 
that a model of sea around the British Islands had been executed 
by Mr. James B. Jordan, of the Mineral Statistics Branch, Home 
Office, and was in the South Kensington Museum of Science 
and Art. That model I have now had the pleasure of seeing. 
It has been carefully and well executed, and cannot but prove 
very instructive to those who examine it. At the same time it 
necessarily leaves much to be desired. The executor has un- 
avoidably been obliged to draw on his imagination in filling in 
many details, where no soundings had been taken from which to 
work his model. The most important place which thus lacks accu- 
racy is the district to the west of the north of Ireland and south of 
Scotland, and thence to the Rockall Bank. Now the hydrographer 
in his chart has not ventured to define the 1000-fathom boundary 
even roughly at this part; the dotted line which indicates that 
depth stops abruptly opposite Donegal Bay, and no attempt is made 
to trace it further to the north. The modeller could not thus stop, 
and has been obliged to supply the deficiency as well as he could. 
It is just in this part that we have one of the most interesting 
features in the outline of submarine Europe, where a tongue of the 
great abyss approaches nearest to our shores. The exact form of 
this tongue and of the slopes which surround it should be accurately 
surveyed. But while this is the most important district which 
awaits elucidation, it is at the same time much to be wished that 
a far more extensive series of soundings should be taken in 500 to 
1500 fathoms all round the western coast.
