Gerarda prevostiana (Eydoux & Gervais, 1837)
(Fig. 11B)
Material studied: None.
Remarks: Included here based on a photographic observation from Rangat, Middle Andaman, that was shared with the author. There are two specimens (ZSI 25351 and ZSI 25352) from Cheppo, North Andaman in the collections of the Zoological Survey of India, Kolkata. Easily distinguishable from Cerberus rynchops by its smooth body scales (vs. strongly keeled in C. rynchops).
Status: Nocturnal, non-endemic and rare.
