GENERAL REPORT ON INVESTIGATIONS IN PORTO RICO. 
21 
At this place we found fishing boats with live-wells, after the manner of those 
in common use at Key West. By eliciting the interest of these fishermen we were 
able to obtain excellent specimens of many important food-fishes, among them several 
species not previously secured. These fish had been caught chiefly in the basket 
traps; a few were taken with hand line. 
The spade-fish (Chcetodipterus faber) was seined here in large numbers. 
Ensenada del Boqueron. — This open bay is only a feAV miles south of Puerto 
Real. Our work on this coast covered practically the entire shore from Puerto Real 
to Los Morillos de Cabo Rojo at the extreme southwest corner of the island. Just 
below Puerto Real is a rocky and abrupt section of the shore terminating in Punta 
de Guanaquilla, a rocky point several feet high, at the north side of Ensenada del 
Boqueron. The entrance to this bay is quite wide, and as but little protection is 
afforded, the surf is usually heavy. Much of this shore, however, is good collecting- 
ground. The best place is perhaps on the north side near the Hacienda Romana of 
Senor Don Pablo McAllister. Dredging stations 6072-6078 were made off this coast. 
Guanica. — Parts of two days (January 28 and 29) were spent at this place. 
Gruanica Bay is one of the best protected harbors in Porto Rico. Inside the harbor 
the shores are in most places of compact sand over which seines can be drawn without 
difficulty. At the upper end the water is shallow and vegetation is abundant. In 
places the bottom is somewhat muddy, but not sufficiently to make shore collecting 
impossible. Animal life, however, was unexpectedly rare in this part of the bay. On 
the northeast side of the harbor more fishes were found, but the bottom was rocky 
in places, which made it difficult to make successful hauls. Specimens of Chilomyc- 
terus and Monacanthus that had not been seen elsewhere were obtained here. Just 
outside the harbor, on the west side, is a coral reef which was particularly rich in 
crustaceans, annelids, and other invertebrates. No dredging was done at this place. 
Ponce. — The harbor at Ponce is merely an open roadstead, and during our stay 
there (January 30 to February 2) the water was too rough for satisfactory collecting, 
except during the early part of the day or in particularly well -protected situations. 
The places visited were the shore and three small islands westward from the pi ay a 
and the reef about the Cardona Island light-house, all of which proved exceptionally 
rich in fishes, mollusks, and crustaceans. A number of new and interesting species of 
each group were obtained. The shore westward from the playa is of compact sand, 
and seining can be carried on fairly well as far out as the little islands about Punta 
de las Cucharas. These islands are low, but dry. About some of them are a few 
clumps of mangrove. About a very small, naked sand island excellent collecting- 
ground was found, and here the type of Doratonotus decoris , a new and interesting 
species of labroid fish, was found among the alga?. An old coral reef here also 
afforded many interesting species. The reef at Cardona Island was visited frequently 
and proved unusually rich in new and interesting forms, among them three new 
species and two new genera of fishes ( Gillias jordani , Coralliozetus cardonce , and 
Auchenopterus cingulatus). No dredging was done by the ship at this place. 
Arroyo. — The surf here was too heavy for seining, but the reef at Punta de las 
Figuras yielded considerable interesting material, and was particularly rich in crus- 
taceans. Other parts of the reef were examined, but proved not so productive as the 
region near the light-house. Considerable commercial fishing is done at Arroyo, chiefly 
with basket traps, though haul seines, hand lines, and cast nets are also used; and from
