NO. 1877. NEW PHILIPPINE SQUALOID SHARES— SMITH. 679 



Type. — Cat. No. 70256, U.S.N.M., a young male specimen 32.5 

 cm. long, taken with a beam trawl January 16, 1908, at station 5111 

 (lat. 13° 45' 15" N.; long. 120° 46' 30" E.), off Sombrero Island, 

 west coast of Luzon, at a depth of 236 fathoms. 



This species appears to differ from S. mitsukurii from Japan in the 

 much more anterior insertion of the ventral fins, longer caudal fin, 

 larger lower caudal lobe, larger anterior dorsal fin, much larger pec- 

 torals, and greater arching of back. The drawing and the descrip- 

 tion^ of that species do not harmonize; and not having access to the 

 types we are unable to verify the difl'erences between the two species. 

 8. megalops from Australia may apparently be distinguished from this 

 species by the more posterior insertion of ventrals and shorter pec- 

 torals, shorter snout, etc. 



LEPIDORHINUS FOLIACEUS Gunther. 



A specimen 31 cm. long was taken with a beam trawl on August 3, 

 1909, between the islands of Leyte and Mindanao, at a depth of 960 

 fathoms. It is a male with very feeble development of claspers, and 

 agrees closely with the description and figure of the type^ from 

 Japan, except that the second dorsal fin is lower and the pectorals 

 are a little longer. 



ETMOPTERUS LUCIFER Jordan and Snyder. 



This species, described from Japan and heretofore known only 

 from that locality, appears to be common in moderately deep water 

 in various parts of the Philippines. The collection contains 21 speci- 

 mens from 14 dredging stations in 9 localities, 10 of the specimens 

 being from 5 stations in Mindanao Sea off the northern coast of 

 Mindanao and 2 others from 2 stations between the islands of Negros 

 and Siquijor. Other specimens are from Balayan Bay, Luzon; Verde 

 Island Passage, between Luzon and Mindoro; off east coast of Min- 

 doro; near Malavatuan Island, between Lubang and Luzon; off west 

 coast of Jolo Island; and between Jolo and Tawi Tawi. The depth 

 range of the specimens taken is 170 to 31S fathoms, and the size 

 hmits are 11 to 28 cm. Males with fuUy developed claspers are 22.5, 

 24, and 27 cm. long; young males, with evident but undeveloped 

 claspers, are 11 cm. long. Another specimen, a fully developed 

 male 29.5 cm. long, has become separated from its label, and no 

 locality or other data can be given for it.
