Typhlonus nasus .

The head of this most remarkable form is somewhat compressed, deep, as thick in the rostral as in the opercular portion; its length is rather more than one fourth of the total. Protuberances formed by projecting portions of the cranium occupy the upper and lateral surfaces of the head; and, more especially, one in front and another on each side of the snout are very conspicuous.
