. Bonner zoologische Monographien. Zoology. 137. Map 27. Distribution of A. gongrorhynchatus. An examination of the only specimen of A. haasi reveals certain differences from gongrorhynchatus which make separating them into different species ad- visable. Nevertheless, until more specimens of haasi are available for study, the question of its status cannot be completely resolved. Description This species is characterized by a moderately depressed, slender body. The lanceolate concavity extending from the frontanasal to the middle of the frontal is not very pronounced.

Nevertheless, until more specimens of haasi are available for study, the question of its status cannot be completely resolved. Description This species is characterized by a moderately depressed, slender body. The lanceolate concavity extending from the frontanasal to the middle of the frontal is not very pronounced. The snout is sharply pointed and swollen at the tip. The nasals are raised. There are three large supraoculars while the fourth one is divided into two. There is one row of granules between the supraoculars and the five or six superciliaries. The anterior loreal is shorter than the second. Four supralabials lie anterior to the subocular. The subocular with a very distinct keel bordering the orbit is separated from the lip and wedged between the fourth and fifth supralabial. There is one keeled supratemporal followed by two or more small ones. The temporals are elongated and somewhat keeled. The ear opening is almost closed off by two or three large scales on the anterior Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bonn, Zoologisches Forschungsinstitut und Museum Alexander Koenig
