Paratypes, all x 96, GG19937. 97, GG19938. 98, GG19939. of the specimens figured by de Greve (1938). The rounded outer lip and semi-straight inner lip are joined below in an even curve and above at an angulation. The aperture tends to be more rounded in specimens with detached peristomes. Remarks. This species differs from D. semituberculata sp. nov. (p. 196) in having much stronger and more regular sculpture and fewer collabral

This species differs from D. semituberculata sp. nov. (p. 196) in having much stronger and more regular sculpture and fewer collabral ribs. Liris tuberculata de Greve is here transferred to Dyris, because of its apparent affinity with D. semituberculata and the close resemblance of its early whorls to those of specimens PIMUZ 491B and 497C from Iquitos. These were figured by de Greve (1938: pi. 5, fig. 37 and pi. 5, fig. 30, respectively) as Dyris gracilis Conrad, but are here reidentified as D. hauxwelli sp. nov. (p. 192). Although these specimens differ from ones from Pichana, the type locality of hauxwelli, in having prominent collabral striae they are unmistakably Dyris rather than Figs 99-102 Dyris semituberculata sp. nov.
