Description. — The six specimens available to me from the Albatross 

 collections are all remarkably constant in the observed characters; 

 the description of one fits almost exactly aU the remaining five. The 

 specimens are very close to the newly described Calliteuthis celetaria 

 Voss, 1960, from off Bermuda, but vary from that species consistently 

 in certain minor characters so that it seems advisable to consider them 

 as members of an Indo-Pacific subspecies of the Atlantic species. 



The mantle is thick, soft, and more elongate than in most of the 

 other species of the genus. In general the greatest width is about 

 one-third of the distance from the anterior border, with the sides 

 somewhat parallel. The width is about 40 percent of the mantle 

 length. Dorsally the anterior margin is only slightly produced 

 whereas it is slightly excavated beneath the funnel. In the posterior 

 third of the mantle the sides are slightly concave but the poste- 

 rior end is blunt. 



The head is about as wide as the mantle width, sharply angled 

 at the neck and with parallel sides. The head is about half as long 

 as the mantle, measured from the base of arm I to the edge of the 

 neck cartilage. The head is somewhat flattened above and rounded 

 below; from the dorsal view it appears squarish. The eyes are 

 distinctly different in size, the left eye about twice as large as the 

 right eye, the pupil also posterior to the right pupil. Slightly ventral 

 and posterior to each eye is a crescent-shaped olfactory crest ter- 

 minating posteriorly in an olfactory bulb. Dorsal to the olfactory 

 crest is a single nuchal fold. 



The funnel is small but strong and without a groove. The locking 

 apparatus is simple. The funnel cartilage is broad, the length less 

 than twice the width, tapered anteriorly and deeply excavated. 

 The mantle member is straight, crescent-shaped in side view, the 

 ridge highest and broadest posteriorly and low and narrow anteriorly. 

 The funnel organ is inverted V-shaped, smooth, pointed anteriorly, 

 with oval ventral pads. There is a distinct and weU-developed 

 dorsal flap or valve just within the funnel opening. 



The fins are large, their length 50 to 55 percent of the mantle length, 

 their width about 70 percent. Individually, the fins are semicircu- 

 lar, the anterior border free. In total view, they are considerably 

 wider than long, forming a transversely oval figure with a distinct 

 notch in the median posterior border. They are dorsally inserted
