each pectoral, — that is, a circular spot of chocolate brown, 
surrounded by a circle of white irregular spots, and some 
irregular white markings in centre, instead of the numerous 
small white markings of the Sandy Eay. It differs from 
the Sandy Kay, in having the surface of the body covered 
with minute spines, directed backwards, — the Sandy Kay 
being smooth, although Yarrell describes it as covered with 
spines. This specimen also differs from the Sandy Kay in 
its tail being long, whereas in the latter it is remarkably 
short ; and, having the characteristic outline and disposition 
of the spines of the Sandy Kay, easily distinguishes it from 
the Sand or Homelyn Kay. 
M'Coy thus gives the description of his fish, which so 
closely agrees with this specimen, that except in one or two 
minor particulars they appear to be the same species : — 
" Spiracles immediately behind the orbits. Skin rough 
above, with the spines largest on the anterior margin of the 
pectorals. Semicircle of six or eight spines round the inner 
margin of the orbits, and a few on the top of the snout ; 
four short rows about or a little before the middle of the 
back (these, I think, are the transverse rows forming the 
triangle at the upper extremity of the rows of large spines) ; 
two rows equally large spines down each side of the tail ; 
four rows of large spines on the tail pointed backwards ; 
central line comparatively unarmed ; all the larger spines 
radiated at their base. Pectorals more abruptly rounded off 
than in the Sandy Kay. Colour uniform, light yellowish 
brown, the large oval spot containing variously shaped 
cream-coloured spots." Such is Professor M' Coy's descrip- 
tion of this ray without a name. 
The following is the description of the specimen now ex- 
hibited : length 12 inches, breadth 6J inches ; from the vent 
to the tip of the snout, 5 inches ; from the same point to the 
tip of the tail, 7 inches (these proportions are very much 
the same as in M' Coy's ray) ; eyes large ; spiracles immedi- 
ately behind the orbits ; skin rough above, thickly covered 
with spines, which are larger on the anterior margin of the 
pectorals, and all of which, even to the most minute, are 
radiated at tlie base. At the upper end of the central line is
