The buccal membrane bears seven lappets and seven supports. 

 The web between the arms is insignificantly developed and very low. 



The photophores are numerous and large on the ventral surface 

 of the mantle, head, and ventral arms. They are scattered over 

 the ventral surface and sides with a close-set single row along the 

 anteroventral margin of the mantle. The ventral mantle light 

 organs are of nearly uniform size and are evenly spaced to the pos- 

 terior tip of the mantle. Only posteriorly near the tip is there a 

 noticeable decrease in size. Dorsally the anterior marginal row of 

 photophores approaches the median line. 



On the ventral surface of the head the light organs are in diagonal 

 rows with a closely set row along the posterior margm of the head. 

 Excluding the organs of the marginal row, there are three photophores 

 in a line down the mid ventral row of the head. Around the right 

 eyelid there is a close-set row of 17 large light organs. The left 

 eyelid has a series of about seven large light organs around the antero- 

 ventral margin and about eight small light organs in two series 

 partially enclosing the remaining portion. 



On arms I, II and III, there appear to be two rows of photophores, 

 those of the dorsal small, those of the ventral large. On IV there 

 are three rows of photophores, only the middle one extending to the 

 tip of the arm. The ventral one extends to the last fifth and the 

 dorsal row on the membrane extends for about two-thirds of the length 

 of the arm in large specimens with five to seven large light organs 

 comprising the row. 



Measurements and indices of six females of Calliteuthis celetaria 

 pacifica Voss, 1962, are: 



Type. — U.S. National Museum. 



Type Locality. — Sta. D5564, 432 m. off Dammi Island, between 

 Jolo and Tawi Tawi, bottom temperature 52.3° F, Sept. 21, 1909. 



Discussion. — The six specimens in the collections show a remark- 

 able uniformity in all characters examined. It is for this reason that 

 I consider the slight differences between the Atlantic C. celetaria and
