68 SIR CHARLES ELIOT ON [May 6, 



The pericardium (text-fig. 3, p. 66) is embedded in the body- 

 wall : its pulsations are visible externally. 



The kidney (text-fig. 3) is spread over the liver, and also on its 

 vential surface, as a number of distinct branching tubes, which 

 continue in front of the liver, lying loosely in the body-cavity. 



The hermaphrodite gland (text-fig. 4, p. 67) consists of three 

 granular, spherical bodies, somewhat on the right side of the 

 liver, one at each end and one in the middle, but not fused with 

 it or embedded in it. The ampulla is large. There is only one 

 spermatotheca. Prostates are absent, and the penis is small and 

 unarmed. 



It will thus be seen that in its internal structure this animal 

 closely resembles Scyllcea. The only important diiference is that 

 the hepatic diveiticula are very small and extend only to the 

 bases of the wings, whereas in Scyllcea (? in all species) they are 

 said to penetrate to the ends of the cerata and into the bi'anchial 

 tufts. I have wondered whether the creature could be a young 

 Scyllcea in which the bifid lobes would svibsequently divide into 

 two pairs of cei'ata, but the size, which is as large as that of most 

 Scyllcece, renders this improbable. Taken in conjunction with the 

 character of the liver, the external differences (the wings instead 

 of two pairs of cerata, the absence of a caudal crest and of flaps 

 behind the rhinophores) seem sufiiciently great to wai-rant the 

 creation of a new genus, which I have named Crosslandia after 

 Mr. Crossland, who dredged the first specimen. 



One of the specimens (PL V. fig. 3) showed marked peculiarities, 

 and is certainly a well-defined variety if not of a distinct species. 

 The body was stouter and the outline more wrinkled and indented. 

 The colour was that of Fucus, with a few pointed sandy projections 

 and coialline purple spots. If it proves to be a distinct species I 

 would call it Cfusca.

A large number of specimens of this remarkable animal were 

 captured on both the east and west sides of Zanzibar in 1901. 

 Alder and Hancock's figiu'e and desci-iption give a good idea of 

 its external appearance; but the coloration is very variable, 

 ranging from clear bright yellow to ashy grey. Sometimes the 

 colour is uniform, but more often the sui-face of the body and of 

 the papill?e is marked with irregulaily disposed spots and blotches, 

 which may be black, white, grey, or sandy. These markings 

 harmonize with the ordinary environment of the creature, and 

 cause it to closely resemble a piece of seaweed besprinkled with 

 sand and pai'tially encrusted with sponges and other animal 

 gi-owths. In full-grown and perfect specimens, which are six 

 inches long or more, the number of papillae seems to be six or 

 seven on each side of the body ; but they are very easily detached, 

 aird few individuals have the two series complete. 



I also found Alder and Hancock's description of the internal
