Sphyrua zygaena (Linnaeus). "Hammer-head." 



Palm Beach. Mr. Wood reports one obtained at Boca Grande 

 Pass, thirteen feet long, Avhich contained 35 young. Mr. Keeley also 

 reports it and Carcharias littoralis at Hawks Park. Mr. Wood 

 noted two other sharks' not preserved, Ginglijmostoma cirratum and 

 Galeocerdo tigrinus, at Boca Grande Pass, the first apparently not 

 before recorded from the east coast. I may also mention that a 

 large example of Rhineodon tijpus A. Smith, was taken at Knight's 

 Key on Jmie 1, 1912, though it has already been recorded by Dr. 

 Gudger. I examined it while on exhibition, in August, 1913, at 

 Atlantic City, N. J. 



Pristis pectinatus Latham. "Saw-fish." 



Two large examples taken at Fort Pierce, and the photograph 

 sent by Mr. Wood. 



.ffitobatUS narinari (Euphrasen). "Stingaree." 



Mr. W^ood obtained it at Boca Grande Pass and sent photographs. 



Lepisosteus osseus (Linnseus). 



I have examined numerous examples in the Philadelphia markets 

 alleged to have been obtained in Florida. Mr. Trimble reported it 

 from the St. Johns River, and also Amiatus calvus, from the 

 Ocklawaha. 



Tarpon atlanticus (Valenciennes). 



]\Ir. Wood obtained this species at New River, Indian River 

 and Boca Grande Pass, and Mr. Keeley reports it from about 

 Hawks Park. 



During 1913, from April 25 to May 7, Mr. Herman T. Wolf made 

 the following interesting measurements (in inches) from 21 examples, 

 freshly killed, from Boca Grande and Captiva Pass, and the Caloosa- 

 hatchee.
