There is no process on its anterior margin at the angle as there is, for example, in Leptolepis normandica. The operculum [Op, Text-fig. 7) is very damaged by crushing or is lacking in all specimens except Watson Colin. No. Judging from this specimen its general shape is about the same as in Pholidophorus. The suhoperculum {Sop, Text-fig. 7) is also only preserved in Watson Colin. No. It seems to be comparatively deep, and the process at its antero-dorsal corner is longer and more pointed than in Ph. bechei. Only the posterior part of the interoperctilum {lop, Text-fig. 7) is exposed in the specimen just named and in 38536, and nothing can be said about its general shape. Lower jaw The lower jaw is partly visible in the holotype and in 38536 and , and Watson Colin. No. Its outhne cannot be determined, but in all specimens mentioned the anterior part of the dentary {De. Spl, PI. 7, figs. 1-3 ; Text-fig. 7) ascends rather gently as in Pholidophorus, not abruptly as in Leptolepis ; from this it may be concluded that the general shape of the lower jaw is also almost as in Pholidophorus. The ridge separating the dental and the comparatively low splenial parts of the dentary is clearly visible. In specimen (PI. 7, fig. 2) the lateral.
