48. Sphyrasna picuda Bl. Schn.

Miguel. On the 29th of the same month the species was seined again at the south end 
of the island, and one specimen, No. 37134, was kept. S. picuda is very abundant here 
and very destructive to weaker tishes. In company with Tylosurus carihbwus and T. 
notaius it scourges the shoals of Harengula and Stolepliorus, driving the panic-stricken 
masses upon the shoals, where the gluttonous pelicans continue the rush of devastation. 
As already mentioned, this species of barracuda is a fair food-fish.

Catalogue Nos. 37094 and 37097. Very plentiful, caught in the seine January 29.
