Indian Stalked Barnnclnt. 'M)i 



concave; niarj^iii directed towards upper latiis feebly exca- 

 vated. Except this plate, all arc widely >cparated troiii the 

 carina. 



Peduncle short, flexed, cylindrical, m itli the base expanded 

 into a small fiat disk, iircfjjiilurly arined uith larj^e hetero- 

 f^cneous plates, whieh arc compressed iVom above downwards 

 and have a sharp ed;ic direeted outwards ; iHjrmally these 

 are covered with a thick smooth membrane. 



Api>endages ^t. — Cirri normal, first widely separated from 

 second, devoid of pigment. Anal appendages short, slender, 

 reaehing ashort distance beyond the junction (jf the two rami 

 of the sixth cirrhus, with six joints and a terminal row of 

 about six stitf hairs. Penis absent. 



Mouth.— Labrum large, feebly bnllate. Maxilla small, 

 with lice edge stx-aight, bristles few and feeble. Mandible 

 very small, with only two main teeth, the outer notched near 

 the extn-mity of its outer margin and with a subsidiary tooth 

 at its base inwards, the inner small and simple. Altogether 

 the mouth-[)arts of this s[)ecics arc feebly developed. There

Localities. — Between Laccadlvcs and mainland, 10:2 2 fath. ; 

 Gulf of Manaar, lUOG fath. and 8j'J-8S0 fath. ; Andamiu 

 Sea, 9;50 fath. On dead Lamellibranch shell ; on skeletons 

 of Gorgoniids and of CuryoplnjUia ; on glassy tiures of 

 Ht/uloncma. Five specimens. 



Var. quadrutuni. 



Upi)er half of snburabinal carina bent into a semicircle. 

 Peduncle with medium-sized plates arranged in ten longi- 

 tudinal series, with about 8 plates in each series. Otherwise 

 agreeing with typical form. 



A single specimen was taken in the Gulf of Manaar at a 

 depth ot between 85'J and 880 fathoms, side by side with one 

 of the typical fcn-m. 



This IS evidently a variety in the true sense of the win-d. 

 Possibly all intermediate stages exist, as some of the typical 

 specimens are nearer that of the variety than others.
