2 MR. E. S. GOODEICH ON A COLLECTION OF 



DECAPODA MYOPSIDA. 



Family SEPIOLINI. 



Iniotetjthis maculosa, n. sp. (PI. 1. figs. 1, 2, & 3.) 



One specimen from the Anclamans, and another from the Persian GuK ; both females.

The mantle is rounded at its apex. The round fins are attached about halfway up the 

 mantle. The band uniting the mantle to the neck is narrower than in In. Morsei. The 

 funnel has a small opening, and a wide base on which are l-shaped sockets. The two 

 muscular bands which unite the base of the funnel above the sockets to the head are 

 less prominent than in Sejnola oi' In. Morsei. There are glandular pads and a small 

 valve inside the funnel. 



The edge of the bviccal membrane is notched, but the lobes are not distinctly 

 marked. 



The first two pairs of arms are rounded ; the ventro-lateral arms are slightly keeled ; 

 the ventral arms are provided with a well-developed keel on the upper edge. They all 

 bear two rows of round suckers, obliquely set on slender stalks rising from a swollen base. 

 The opening of the sucker is wide ; the horny ring has an ornamented surface and a 

 smooth edge. 



The tentacular arms are flattened, and a groove runs down tbe inner surface. The 

 club is of great Iciigth, slightly enlarged, provided with a lateral membrane on both 

 sides, and a large niimber of minute suckers in eight rows. Each sucker is nearly hemi- 

 spherical, set obliquely on a long slender stalk (fig. 3). The papillary area of the horny 

 ring is wide, and the edge armed with alioiit 15 teeth (fig. 2). 



The ground-colour of the first individual is pale brownish yellow, inclining to orange 



* In the following descriptions the terms " upper " and " lower " are used to denote the surfaces generally called 

 " dorsal " and " ventral ; " since, strictly speaking, they do not correspond to the morphological dorsal and ventral 

 surfaces.
