Oocorys Fischer.

Stat. i,"- 7 S., 150° 33 .4 K. Ceram Sea. [914 M. Fine grey .nul green mud. 1 Spec. 



'lobosely ovate, moderately ventricose, rather strong, white under a yellowish 



epidermis; whorls about 5 , (nucleus ones worn) convex, with a distinct suture and with strong 



of which there are six on the penultimate whorl; 22 on the last one, including the 



eparated l>y interstices, with a few exceptions about as broad as the 



themselves, the uppermost liration borders the suture and is separated from the second 



by a broader concave interstice, giving it a channellike appearance; the interstices and in 



ree the lirae, are crossed by radiating striae, which are coarser on the upper whorls. 



Aperture oblong-ovate, angular above, ending in a broad canal directed towards the left, 



columellar margin with a rather strong layer of enamel, spread over the bodywhorl; it is 



grooved by the lirae and covered with microscopic granules-, columella rounded, curved, strongly 



bent to the left along the canal; right margin nearly regularly curved, with an angle, corres- 



ponding to the second lira, and with an external rib, expanded and grooved interiorly; these 



grooves extend in the interior of the shell, which is porcellaneous. 



( )perculum as in the typical species, reddish-brown, with a shallow groove along the 

 rigrht marefin. 



Alt. 38, lat. 27; apert. alt. incl. perist. 28, lat. [4 1 /,. 



This species is less globose than O. sulcata Fischer (Journ. Conch. 1883, p. 392) with 

 fewer lirae (6 in the penultimate whorl, instead of 8 to 12) the radiating striae seem to be 

 much weaker than in sulcata, at least than in the "Challenger" specimen, where the interstices 

 are much broader (Boo<; Watson: "Challenger" Gastropoda, PI. 17, fig. 11). In Benthodolium 

 (= Oocorys) abyssorum Yerrill (Transact. Connecticut Acad. Vol. VI, 1882 — 85, p. 177, PI. 31, 

 fig. 1 2 i the spire is much higher if compared with the aperture, the lirae are much more 

 numerous, and the interspaces much broader, the canal much straighter. It appears rather 

 doubtful to me, that these specimens should belong to the same species, unless it be exces- 

 si vel y variable. 1 think the differences enumerated above, will be sufficiënt to separate shells 

 of such a remote provenience.
