date of hauling after October 28th. The exact data concerning 

 the October surface hauls are given in the accompanying table. 



* station A is located at 32° 23;? N. 117° 19;2 W on a line extending WSW of 

 South Coronado Island at a point approximately three and one-half miles from the 

 island, where the water is 350 fathoms in depth. 



Station B is located at 32° 22^4 N, 117° 2i;2 W on the same line approximately 

 two miles farther seaward, where the water is 700 fathoms in depth. 



Owing to the .small number of specimens obtained and owing 

 to the fact that their capture was limited to four days of October, 

 1911, very little regarding their manner of distribution is deter- 

 minable. However, table 13 reveals one interesting fact, namely, 

 that the species was more abundant at station B than at station 

 A, i.e., at the location farthest from land. Altogether 171 speci- 

 mens were obtained from station B and 62 from station A. or an 

 average of 22 per hour at B and 7 per hour at A. Furthermore 

 this relation holds when the corresponding times of day are 

 compared, as in table 14.
