The proximal margin is slightly irregular, but lacks definite teeth. The inner chitinous rings of the dactyl suckers have generally 4 slender, widely separated truncate teeth on the distal margin, with 1–2 smaller teeth on each lateral margin. The dactylus is short and bears from 22–32 small suckers arranged in 4 longitudinal rows. Hooks first develop at approximately 40–50 mm M.L.

In young specimens, the marginal series are complete. The manus bears 2 rows of large hooks with 1–2 suckers in each marginal series at the proximal end. A minute keel is present at the extreme tip of the club.

The clubs are only slightly expanded and have narrow, potective membranes which extend the full length of the club along both margins and contain very broad trabeculae. A low web is present which is most noticeable between arms I–II. Therefore, it appears that this modification of the arm tips is a type of hectocotylization. armata (also a male) shows the same feature. This distal area gives the impression that the arm tips have been lost and are in a state of regeneration however, these tips are affected identically among opposite membrs of arms I and II and in all of the larger males (3 specimens). In the larger of the males, the tips of arms I–II narrow abruptly and possess very small suckers in 2 rows. The largest suckers of arms IV occur in the middle of the arms. The suckers are globular, but have rather large apertures. Narrow lateral keels are present throughout the length of arms IV. Arms I–III appear to have low, gelatinous aboral keels. All arms possess large trabeculate protective membranes which are better developed on the ventral border of each arm. The arms are relatively short, but muscular.

From the skin over the midposterior surface of each eye arises an “olfactory” papilla which has a cup-shape terminal portion set on a swollen stalk. The eye opening is rather small and has an anterior sinus. In specimens up to about 60–65 mm M.L., the eyes are set on stalks. The eyes nearly touch each other in the ventral midline. The head consists almost entirely of 2 very large, bulging eyes which are directed slightly forward. The funnel is free from the head laterally. The dorsal pads are nearly oval in shape. Three large, slightly flattened papillae are present, one on each lateral arm and one on the anterior midline. The dorsal pad of the funnel organ has an inverted U-shape with rounded lateral arms. The funnel is moderate in size, reaching approximately to the level of the midpoint of the eyes. The fins become very antenuate posteriorly, but extend to the tip of the pen. in specimens greater than 100 mm M.L.), and lack anterior or posterior lobes. in specimens greater than 100 mm M.L.), and slender (width 28–35% of the M.L. The fins are lanceolate, extremely long (41–47% of the M.L. Each of the latter 2 areas is marked by a fiat cartilaginous pad with 2–A small tuebrcules at its anterior end. The very thin but muscular mantle is fused to the head at the nuchal region and to the lateral corners of the funnel.
