Neck folds in Stenocercus. Illustration by L. Analla Pugener. Antegular fold.âThis fold traverses the ventral sur- face of the neck anterior to the gular fold. Longitudinal neck fold.âThis longitudinal fold ex- tends along the ventrolateral part of the body from the posteroventral edge of the ear to the forelimb. Postauricular fold.âThis fold Ues immediately behind the ear usually is confluent with the longitudinal neck fold and the supra-auricular fold. Rictal fold.âA fold ventral and anteroventral to the ear. POSTHUMERAL AND POSTFEMORAL POCKETS Type 1.âPocket absent, no apparent skin modifica- tion. Type 2.âA noticeable skin modification, such as bare patch of skin, a series of wrinkles in the skin, or a shallow depression lined with scales different from surrounding body scales. Type 3.âA shallow pocket, similar to Type 2, but with the addition of an overhanging fold of skin or thickened border. Its depth is generally less than half the diameter of the opening. Type 4.âA moderate to deep pocket usually having a broad circular opening (narrow in Stenocercus aculeatus); its depth is greater than half the diameter of the opening. Type 5.âA moderate to deep pocket with a narrow, slitlike opening; its depth is generally greater than half the greatest diameter of the opening. This type was observed only in postfemoral pockets in the species studied. SPECIES ACCOUNTS Stenocercus aculeatus (O'Shaughnessy) Leiocephalus aculeatus O'Shaughnessy, 1879:303.
