Heteropengia subramosa. Canal apertures about 5 in 5 mm. No oscula. Marin & Lincoln Cn. Heteropengia kessoti, Canal apertures 6 to 8 in 5 mm. Oscula nearly circular, at intervals of 8 to 20 mm. mm rounded by radiating channels. Labuan K7. Heteropengia aspera. Very irregular or with strongly undulated labiate extraneous calypti masses, several inches in length. Canal apertures often subquadrate about 7-8 in 5 mm. Well sepa- rately arranged and more nearly equal size than in preceding species. Well mouths of canals in some areas frequently displayed in a radial manner, but no osculum in center. Marin & Lincoln Cn. Hindia parva. Colby, McKinney. Styptopengia labrinttica. Labrynthically interstining vertical candellae, .3 mm thick, separated by tate- ries, almost linear interspaces with hue + than an open space 1 mm in length. Vertical fracture shows that inter- twining is produced by connecting processes on sides of laminas. There are usually rounded in crosssection and very unequal size, and occur at frequent but irregular intervals. Numerous small punctures. Labuan K7.
