Hemipenis The following description of the everted hemipenis of Dipsas oreas is based on specimens from northwestern Peru (ANSP 31778-81, 31783, 31785-86; all field everted). The organ is fully capitate, and the capitulum is calyculate and very slight- ly bilobed distally. The calyces are sur- mounted by a dense array of fleshy papil- lae. With the exception of the most distal papillae, the tips of the papillae are spi- nulate (, they have mineralized tips). The sulcus spermaticus divides at the base of the capitulum and has centrolineal branches that extend nearly to the center of each of the small lobes. A large nude pocket approximately one third the length of the organ is on the lateral surface of the organ, extending from the base to the en- circling battery of spines around the mid- section. The pocket is bordered by a thick lobe on each side. These lobes are orna- mented with tiny spines, but otherwise, the basal portion of the organ on both the sulcate and asulcate sides is nude or with scattered minute spines. The asulcate side of the organ has a pair of extremely large spines just distal to the basal nude portion, distally followed by a gap ornamented with tiny spines and then a dense battery of large, thick spines oc-
