Lastly, X-ray photographs of Scopelarclms cavei , S. guentheri, Neoscopelarchoides dubius , N. elongatus and Evermannella balbo have not revealed the presence of intermuscular bones. (These show up quite clearly in X-ray photographs of paralepidids, Anotopterus and Alepisaurus.). Text-fig. 9. a, transverse section through the trunk muscles of Anotopterus pharao, showing the intermuscular bones (imb.) (x9'3); b, some of the larger intermuscular bones associated with the first three vertebrae of Omosudis lowei (x io-6) = dorsal ligament. Distensibility of stomach and body-zuall Evermannella, Omosudis, Anotopterus and Alepisaurus are among the alepisauroids capable of swallowing very large prey. Alcock (1899) has a drawing of Evermannella atrata very much distended with a large squid, while in the Discovery Collections there is a specimen of E. indica with a gono- stomatid fish folded up in its stomach, the length of the prey being appreciably longer than the length of the predator's abdomen. The capacity of Omosudis for swallowing large prey is well known since Gunther's (1887) account of a Sternoptyx in the stomach of one individual, victim and predator being equal in bulk. Anotopterus also has a highly distensible stomach and body-wall, as the presence of two large Notolepis coatsi in the specimen described earlier (p. 321) must indicate. Alepisau
