At first glance, I thought this adorably cute sleeping lizard was another of the Dusky Earless Agamas that I had seen so often in Malaysia. But the proportions seemed off: the head was too big, and the tail a little short, and the body a little bulky. Back at my room the next day, I consulted the books I had brought and guessed that it was Phoxophrys nigrilabris instead. Later I had this opinion confirmed by a knowledgeable herpetologist.

My Travelogues and Trip Lists page includes a complete list of the herps I saw in the wild on this trip to Malaysia, as well as a travelogue of the trip.
