Family GALEID. 
2. Galeus lunulatus (Jordan & Gilbert). Garo. 
Rather common at Mazatlan, where the original types 
were obtained by Dr. Gilbert. 
3. Galeocerdo tigrinus Miller & Henle. 
Recorded by Dr. Gilbert, from Mazatlan and from San 
José de Guatemala; not seen by us. It has not been 
compared with the Brazilian type of the species. 
4. Scoliodon longurio (Jordan & Gilbert). 
Rather common in the harbor at Mazatlan, where the 
original types were taken by Dr. Gilbert, who also found 
the species at Panama. 
5. Carcharhinus ethalorus Jordan & Gilbert. 
Original described from Mazatlan; not seen by us. 
Also recorded by Dr. Gilbert, from Panama. It is not 
likely that Carcharhinus limbatus occurs on the Pacific 
Coast. Probably this related species has been mistaken 
for it. 
6. Carcharhinus lamiella (Jordan & Gilbert). 
A very young specimen with a deformed tail was ob- 
tained by us at Mazatlan, the first record of the species 
from that port. 
7. Carcharhinus fronto Jordan & Gilbert. 
This large shark is not uncommon about Mazatlan, 
where the original types were taken by Dr. Gilbert. No 
specimens were seen by us, but the species is said to be 
common in the surf about the Olas Altas. It is said that 
during the time that Mazatlan was occupied by French 
soldiers a number of these were killed by the sharks 
while bathing in the surf.
