Molgula pannosa Verrill, sp. nov. Figure 2. 



Body subglobular, or a little elongated, somewhat compressed 

 laterally, entirely covered, except the ends of the tubes, 

 firm and thick covering, composed of frag 

 meuts of shells, echini, zoophytes, worm 

 tubes, foraminifera, grains of sand, pieces 

 of sea-weed, and other debris, 

 face of the integument, when the foreign 

 matter is removed, is densely covered with 

 small granule-like papillae, which give rise 

 to very abundant, long, fine fibrous pro- 

 cesses, by which the foreign matters are en- 

 tangled ; the basal portion of the tubes is 

 covered with similar processes, though less numerous, which 

 decrease toward the end, leaving the terminal portion nearly 

 smooth. The tubes, which arise close together, are short, con- 

 ical, a little divergent. The anal tube is a little longer than 

 the branchial, swollen at base, tapering, and rounded at the end, 

 which has a very small square aperture. The branchial tube 

 is about the same in size, but a little shorter, subcylmdncal, 

 scarcely tapering, with six, small, prominent, acute lobes or 

 papillae ; alternating with these are six much smaller ones, in 

 contraction the tubes can be wholly withdrawn, and then the 

 body looks like a more or less irregular ball of dirt. 



In life the color of the clean inte,gument is a dull, dark, gray- 

 ish green ; the tubes lighter, or dull olive-green.
