Family GALEID^. 



2. Galeus lunulatus (Jordan & Gilbert). Gato. 

 Rather common at Mazatlan, where the original types 



were obtained by Dr. Gilbert. 



3. Galeocerdo tigrinus Miiller & Henle. 



Recorded by Dr. Gilbert, from Mazatlan and from San 

 Jose 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 aethalorus Jordan & Gilbert. 

 Original desci'ibed from Mazatlan; not seen by us. 



Also recorded by Dr. Gilbert, from Panama. It is not 

 likely that Carcharhinus limbatiis 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.
