 ? Bascanius tcedifer Schiodte, Natur. Tydsskr., v, 209,1867 (free-swimming oceanic 



larvae). 



Habitat. — Mediterranean Sea. 



We have examined three specimens of this rare species, obtained at 

 Palermo by Professor Doderlein. As already noticed, this is a genuine 

 member of the genus usually called Aphoristia, having no lateral line. 

 These three specimeus have the body nearly uniform in color. They 

 correspond to the Ammopleurops lacteus of European authors. A speci- 

 men in the museum at Cambridge from Naples is somewhat mottled 

 and represents the nominal species Ammopleurops pictus. 



128. SYMPHURUS MARGINATUS. 



Aphoristia mmginata Goode & Bean, Bull. Mus. Comp. Zool., sii, 153. (Off St. Vin- 

 cent, etc.) 



Habitat. — West Indies. 



This species is known only from the original types, taken in deep water 

 (94 to 324 fathoms) in the West Indies. 



129. SYMPHURUS ELONGATUS. 



Aphoristia omata var. elongata Giinther, Fishes Centr. Amer., 1869, 473. (Panama. ) 

 Aphoristia elongata Jordan &, Gilbert, Bull. U. S. Fish Comm., 1882, 111. (Panama.) 



Habitat — Pacific coast of tropical America. 



This species is not uncommon on the Pacific coast of Central America, 

 where it represents the closely related Symplmms plagusia. Its relations 

 with 8t)mphurus atricauda are still closer.
