The measurements and indices of four females of Sejpia prionota, 

 Voss, 1962, (those of the holotype being given first) are: 



Type.— USNM 575326. 



Type Locality. — Off Sirun Id., Sulu Archipelago, Tawi Tawi 

 group, Sta. D5151. 



Discussion. — This species seems to be distinct from any of the other 

 species of Sepia so far recorded from the Indo-Malayan area. It does 

 not seem referable to any of the species mentioned by Adam (1939b) 

 in his monographic treatment of the species, nor does it conform to any 

 of the Japanese species given by Sasaki (1929). The presence of the 

 sawlike keels on the arms alone seems sufficient to separate this species 

 from all others presently Imown from the Indo-Malayan region.

Material.— 6 9 9, ML 26.0-82.0 mm., from Canmahala Bay, 

 Ragay Gulf, Luzon, dynamited from coral reef in 55 m.. Mar. 11, 

 1909; USNM 575351. 



Description. — The mantle is somewhat slender, forming an oval 

 outline. The anterior margin is produced as a broad triangular lobe 

 in the midline, rounded at the apex, the margin scooped out on each 

 side of the lobe. Ventrally the margin is slightly excavated beneath 

 the funnel and straight, the sides curving downward. The posterior 

 end is bluntly pointed. The mantle is widest at about the midpoint. 



The fins are very narrow, widest at the posterior third. They 

 originate almost at the anterior margin and terminate on either side 

 of the end of the mantle. They are not strongly lobed but are free 

 at each end.
