larve). 
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 specimens have the body nearly uniform in color. They 
correspond to the Ammopleurops lacteus of Kuropean 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 marginata Goode & Bean, Bull. Mus. Comp. Zool., xii, 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 ornata 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 Symphurus plagusia. Its relations 
with Symphurus atricauda are still closer.
