Caiman on with sides expanded in the lower part to four to five timestheir deptii in the upper part (as against about three times inthe figure of M. sub carina turn), transverse width of upperpart (in large specimens) about one-third of that of basalmargin ; basal margin, as seen from the side, equal to orslightly longer or shorter than that of scutum. Inner septumwith upper edge concave but not distinctly bilobed, not pro-jecting when the detached carina is seen from the side. Peduncle very short, its diameter much less than that of Fiar. Megalasma (Glypteasma) orientate, sp. n., holotype. A. Lateral view. B. Basal angle of scutum, inner Carina, inner surface. the peduncular orifice, and attached some distance above thebasal margins of scuta and carina. A pair of long tapering filamentary appendages are attachedside by side on the anterior part of the dorsal surface of theprosoma. A short finger-like appendage is placed close tothe base of the first cirrus. Rami of first cirrus with 9 and11 segments respectively. Caudal appendages very shortstumps, with a few apical seta?.
