largest number of e<>'g's found by Patio was l/Jlo; the eggs are relativelj'' 

 large. They are hatched in about eight days. 



The species frequents clear water. Its length varies from four inches in 

 the Danube to six inches in the Neckar. Its scales are sometimes collected for 

 the manufacture of artificial pearls. 



The skeleton includes thirty-eight to forty vertebra.^^ of which eighteen 

 are in the thorax and twenty-two in the tail. 



The intestine is about as long as the fish, and forms two folds. The food 

 is partly vegetable, but consists mainly of insects, worms, and small molluscs. 

 The pharyng'cal teeth are two in the outer row, and five in the inner; the 

 formula, according to Dr. Giiiither, is 5'2 — 2"-i[5]. The teeth are smooth, 

 and have their extremities hooked. 



This species is not known in Britain, though Blanehard speaks of it as 

 a common English fish; but is found in France, Belgium, Holland, North and 

 South Germany, Switzerland, and Austria, and extends into the south-west

In Paris it is commonly known as the Smelt of the Seine, though belong- 

 ing to a different family. In every country it has many local names. In 

 some parts of France it is termed the Sperlin; and Fatio has referred it to 

 a new sub-genus, which he terms Sperlhius, regarding it as a connecting 

 liidv between Abramis and Alburnus. The number of pharyngeal teeth ou the 

 right side, which is almost constant, separates it from Alburnus. 



The fish is liable to a disease in which blisters or gassy vesicles appear on 

 the opercular plates, at the base of the fins, at the back of the mouth, and over 

 the eyes. Another disease is due to a parasite allied to DipJofdomiiDi cuiicnla, 

 which produces black spots over the body and in the mouth. It is also liiil)le 

 to tnjie-worm and other parasites.
