Hemipenis of Geodipsas infralineata (MCZ 181153; specimen from thie RNP). Fully evetled organ In sulcate (left) and asulcute (rigfit) views. The asulcate view is shown in three-quarters view to accommodate the strong flexure of this particular organ. The flared tissue at the base of the organ is simply the tissue below the ligature tying off the base. spermaticus divides at the suture between subcaudals 4 and 5 (approximately 65% di- vided) and extends distally in the lateral wall of the retracted organ (centrolineal in orientation); the branches extend to sepa- rate nude areas on the apex of the organ. The spines are much denser on the sulcate than on the asulcate side, are present be- tween the branches of the divided sulcus, and appear to be arranged roughly into longitudinal rows. The form of the spines and the relative distribution of spine sizes appears similar to that described for G. vauerocegae, including the presence of a patch containing seven to eight enlarged spines basally on the asulcate side. As in G. vauerocegae, the sulcus branches end in nude areas separated by tufts of spines, although the nude portions seem less ex- tensive than in vauerocegae (but perhaps would be equivalent upon eversion). The distal ornamentation, spine size and distri- bution, and overall appearance of the hemipenis of G. procterae are probably very similar to that of G. vauerocegae in the everted state. Geodipsas depressiceps (MCZ 9261, Retracted and Everted). Bogerts (1940: 38) description of the hemipenis of G. de- pressiceps (based on a specimen from the Congo) is here repeated in its entirety: "Not bifid [, nonbilobed], extending to the seventh caudal, but with the sulcus bi- furcating at the second. Near the base are about thirteen slightly enlarged basal hooks in a V-shaped arrangement, with the apex distally at the sulcus
