CEPHALOPODS OF THE PHILIPPINE ISLANDS 59 



Measurement and indices of five specimens of Sepiola trirostrata 

 Voss are: 



The color in alcohol is a brownish yellow. The mantle, especially 

 ventrally, is liberally spotted with minute round dark brown or black 

 chromatophores. These are larger on the ventral surface of the head. 

 Arms III are tinted a deep rose or pink, paler in some specimens. 

 The outer surface of I, II, and III has a single row of about eight 

 large brownish chromatophores, whereas IV has a double row of small 

 ones. 



The ink sac appears to be shaped like two kidneys with an indefi- 

 nitely defined light organ on each lobe. 



The spermatophores are small, 2.2 mm. in length. Though re- 

 sembling those of both Sepiola parva and aS'. birostrata, they are more 

 slender than either, the coiled part of the sperm reservoir is shorter, 

 the straight part longer, and the midorgan is somewhat difl^erently 

 constructed. 



Type.— U.S. National Museum. 



Type locality. — Off Nogas Point, Panay. 



Discussion. — The peculiar construction of the hectocotylized arm 

 serves to separate this species from both of the other Indo-Pacific 

 forms. The structure of the spermatophore also is distinctive. 



Distribution. — Known only from the type locality.
