PANAMIC AND WEST INDIAN ECH1NID FAUNA. 





six stations, two species; at three stations, three species; at five stations, 

 four species ; at two stations, five species. 



On the West Indian side Echini were collected at one hundred and 

 seventy-eight stations. At ninety-eight stations only one species was 

 found; at twenty-nine, two species; at twenty-four, three species; at 

 seven, four species; at ten, five species; at four, six species; at five, seven; 

 and at one station thirteen species. In the West Indies by far the greatest 

 number of the hauls were made along the continental slope, and compara- 

 tively few in the abyssal region ; while in the Panamic district compara- 

 tively few hauls were made along the continental slope, a larger proportion 

 being made in the abyssal region. So that the comparisons here made will 

 probably be somewhat modified after a more extended survey of the 

 Panamic continental slope has been made. 



The following lists taken at characteristic points will give an idea of the 

 association of the species of Echini on the West Indian continental slope.
