ROOM XI.] 
the anterior edge of the pectoral fin expanded like two 
horns. 
The Electric Ray ( Torpedo ) is peculiar for its fiddle¬ 
shaped body. 
The last family of fishes is that of the Lampreys ( Petro - 
myzulce), whose skeleton is the most imperfect of all the 
vertebrated animals. Their body is long, slender, and 
cylindrical, ending in a circular mouth, and destitute of 
pectoral and ventral fins. The true Lamprey ( Petromyzon ) 
has seven branchial openings, whence their vulgar name 
Seven Eyes, and the skin under the tail forms a kind of 
fin. Their mouth is armed with teeth. 
The Gastrobranchus ( Gastrobranchus) differs from the 
Lamprey, by the tongue only being armed with teeth, like 
the Lobworms. These animals emit such a quantity of 
mucus through the pores of the lateral lines, that it con¬ 
verts the water in which it is placed into a jelly. 
Cases No. 9—23 contain Fishes preserved in spirits. 
The Table Case in the centre of the room contains 
a collection of dried fishes, arranged as those in the Wall 
Cases. 
On the Walls over the Cases round the Room, 
are placed a series of the horns of mammalia belonging to 
the family Bovidae. Amongst them are 
The Arnee (Bos Arne) of India; the African Buffalo; 
the Gour (Bos Gour) of India; the Musk Ox ( Bos mos - 
chatus ), and some Horns of domestic cattle. Amongst the 
latter is a pair of horns of the African Ox of very large 
size, but exceedingly light, the core being very cellular; 
the Ibex (Capra Ibex), from Egypt; the Wild Goat; 
the Jemlah Goat ; varieties of Sheep, especially the Four 
Horned Sheep: the Koba ( Antilope Senegalensis ), from 
the interior of Africa ; the Gazelle (Antilope Dorcas ) ; 
Indian Antelope (Antilope Cervicapra ); Saiga (Antilope 
Saiga); Impoofo; Caffrarian Oryx; Roan Antelope ; Blue¬ 
faced Antelope; White-faced Antelope, &c. 
Between the Windows are the Spike of a large Saw- 
Fish, and a large Rhinobate, from India; and, on the 
sides of the Door, a Shark, and a large specimen of a 
Torpedo, found on the coast of England. 
Over the Cases 9—12, on the right hand of the fire¬ 
place, is a fine specimen of the Tetrapturus Herschellii,
