1907.] FROM ZANZIBAR AND EAST AFRICA. 455 



A specimen measuring 12 mm. from the posterior end of the 

 mantle to the eye, and with arms from 25 to 30 mm, in length, 

 closely resembles a small Octopod obtained by Professor Herdman 

 from the west coast of Ceylon and recorded as Polypus E in the 

 Report on his investigations. The upper surface is slightly 

 granular and there is a minute papilla above and behind 

 each eye. 



Polypus L. 



Polyjnis L, Hoyle (:05) p. 980, figs. 147-150. 



Locality. — Zanzibar, Wasin, 10 fathoms, dredged near N.E. 

 mouth of harbour ; one young specimen, S [180]. 



Previous record. — Hulule, Male Atoll {Hoyle). 



This is veiy near the young specimen from the Mai dive 

 Archipelago, which I have called Polypus L. It has the tliree 

 conspicuous chromatophores on the ventral surface and the equi- 

 distant ones on the oviter surface of the arms. 



Polypus M. (Text-figs. 130, 131.) 



Locality. — Zanzibar, Chuaka Bay, dredged April 18th, 1901 ; 

 two young specimens, sex ? [173, 174]. 



These two young specimens closely resemble two from the Gulf 

 of Manaar, called Polypus H in my Report on Prof. Herdman 's

collections from Ceylon (:04:, p. 197). Their chief characters are 

 a rounded saccular body with a deep groove in the middle line 

 below, a single papilla over each eye, and a single row of large 

 chromatophores up the outer side of each arm, and two, instead 

 of three, conspicuous chromatophores on the lower aspect of the 

 mantle. There are rudiments of a few papillse on the dorsal 

 surface of the mantle of the larger specimen.
