The penis is long, straight, and tubular and contained about six 

 spermatophores which were 6.1 mm. by 0.3 mm. Details of structure

The buccal membrane is seven-pointed, smooth, and bears two to 

 eight suckers on the tip of each lappet. 



The gladius is narrow (GWI 10.3) with almost straight margins, the 

 lateral portion of the vane thickened and darkly colored. 



Measurements and indices of two males of Doryteuthis singhalensis 

 (Ortmann) are: 



Type. — Not traced. 



Type locality. — Ceylon. 



Discussion. — Adam (1954) has given a detailed description of this 

 species from the East Indies and has discussed briefly the status of 

 D. spectrum, and D. arabica, which he considers may represent geo- 

 graphical races along with D. singhalensis. Much more work must 

 be done before their status can be decided. 



Geographical distribution. — Ceylon (Ortmann). India; East 

 Indies (both Adam). Philippines!
