Type material. Lectotype — RGM St10344 ( Jung 1974). The type measures 37.1 mm in length with a width of 13.1 mm ( Jung 1974).

Type locality. Kai Puru, Naggulan, Djokjakarta , Java [Priabonian] .

Diagnosis. The shell has a stout but acute teleoconch. The greatest diameter of the shell occurs at the adapical end of the aperture. The body whorl is slightly concave at the lower half. The columella is bent to the left and backward. The callus of the labrum reaches the apex. The labrum is slightly thickened and terminates well above the columella. As a juvenile, the shell has a slight spiral groove near the apex. The adults have distinctive sculpturing on the lower half of the body whorl. The growth lines of the shell form a reticulate spiral pattern.

Distribution. EOCENE—Priabonian— Indonesia Kali Puru, Nanggulan, Java ( Martin 1914; Jung 1974).

Remarks. Seraphs squamosus is uniquely shaped among the Seraphs with its triangular spire and broad body whorl.
