ENTEROPNEUSTA. 

 Balanoglossus, sp. 



A species of Balanoglossus was found this year burrowing in the 

 sand-flats on the north side of Long Bird Island. It was about 

 150 mm in length. Its color was ocher-yellow to dull orange-brown. 

 Its structure has not yet been studied with care. No species of this 

 group has hitherto been reported from the Bermudas. 



LEPTOCARDIA. 



Branchiostoma Caribceum Sund. Lancelet.

Hitherto no locality for this Amphioxus has been known at Ber- 

 muda except on the west side of the inlet at the Flatts, where it was 

 first discovered by Mr. Goode, in 1876. This year we dredged it on

a bottom of hard shell-sand and mud, in Castle Harbor, about one- 

 half a mile north of Castle Island, in 15 to 20 feet of water. This is 

 also one of the localities for Strombus gigas. Another similar 

 locality, near Tucker's Island, in Great Sound, where Strombus 

 </'';/"■•< is found, would very likely also yield the lancelet. 



FISHES. 



Carcharinus platyodon (Poey). Shark. 



Squalus platyodon Poey, Memorias, ii, p. 331, 1861. 



Careharias platyodon Jordan and Gilbert, Proc. U. S. Nat. Mus., p. 243, 1882. 



Carcharinus platyodon Jord. and Ever., Fishes N. Amer., i, p. 39, 1890. 



A dead specimen of this specie-, about four feet long, was found 

 on the south beach near Tuckerstown, in April. It was badly 

 decomposed and only some teeth could be preserved. From these 

 the species has been identified by Mr. Samuel Garman. The color of 

 the upper side was grayish blue ; white below. 



It has been recorded from Cuba, Texas, and the Gulf of Mexico, 

 where it grows to a much larger size (10 to 15 feet long).
