JV. brevispinosa, or remarkably long as in JV. corona. Some of the species 

 are curiously winged on each side, as in the JV. dilatata and latissima. 



There is scarcely any limit to the geographical distribution of the Neri- 

 tina, save in the frigid and cold temperate zones. The genus is repre- 

 sented in an humble, but very prettily painted condition on our own coast, 

 it is plentiful in the West Indies, and is found throughout the great con- 

 tinent of North, South, and Central America. It is not less abundant in 

 the Eastern world. Magnificent specimens were collected by Mr. Cuming 

 in the Philippines, among which the JV". labiosa, selected for illustration is 

 perhaps the largest. In Sumatra and other Islands of the Oriental Archi- 

 pelago, in India, and in South Africa, the Neritina are also more or less 

 plentiful.
