(pl. xxiv, fig. 11) closely resembles that of L. pealiz, Verrill (1882, 
pl. xxviii, figs. 6-8). The frontal lamina of the upper mandible (pl. 
xxiii, fig. 9) curves more upwards than in that species and the 
posterior end of the palatine lamina has a median indentation. 
The lower mandible (pl. xxiii, fig. 9) has the notch near the ros- 
trum less marked than in L. pealid and the lower edge of the 
gular lamina is indented. 
Distribution.—Indo-Malayan Region. 
Type.—In Hamburg Museum.

The long, slender body readily distinguishes this species from 
L. indica. Order of arms 3,4,2,1. Rings of arm suckers usually 
with eight teeth (sometimes seven or nine) on the distal margin, 
and the rest of ring smooth. At the base and distal portion of 
each arm the teeth are short, broad and blunt, elsewhere they are 
rather narrow, pointed and slightly curved. Distal rings often 
have only four to six teeth, and a sucker at the base of the fourth 
right arm has eleven teeth. Sixteen rows of suckers occur on the 
proximal part of the hectocotylized arm, the two pairs immediate- 
ly preceding the papillae being placed on long stalks. Pfeffer 
describes the tentacular rings as possessing forty teeth. Thirty- 
one is the largest number I could find on any tentacular ring, but 
this specimen is considerably smaller than the type which has a 
mantle-length of 284 mm. A marginal sucker, intermediate in 
size between the large and the distal club suckers, possesses 
eight pointed teeth separated by the width of the base of a tooth, 
and covering the distal half of the ring. Suckers are present on 
the buccal membrane which is seven-angled.
