Remarks.—Dall (1890, p. 38) apparently had two specimens available when he described L. tenninula. He commented that the species is rare. On the label accompanying specimen USNM 97338 it says "fig- ured syntype", which is here selected as the lectotype. The label of specimen USNM 647034 says "measured syntype". This specimen is the paralectotype (Text-fig. 58). The present writer was first confused about the identity of these specimens until he found out that Dall had given the (approximate) measurements of the un- figured paralectotype in the original description but not those of the lectotype. Whenever preserved, the protoconch of this species consists of volutions and therefore represents a constant feature. The last volution of the protoconch is sculptured by slightly opisthocline axial riblets. The. 1 Text-figure 60.—Lepicythara tenninula (Dall). NMB H 18117.

On the other hand, the number of axial ribs per teleo- conch whorl is somewhat variable with the result that these axial ribs may be alined on successive whorls or not.
