A. C. Stokes—Fresh-water Infusoria. 313 
Art. XLIT.—WNotes on some apparently undescribed forms of 
Fresh-water Infusoria. No. 2 ;* by Dr. AuFRED C. STOKES. 
With Plate III. 
THe subjoined fresh-water Infusoria which, so far as I am 
able to ascertain, have not been previously observed and are 
Consequently undescribed, have, with a single exception, been 
obtained from the shallow ponds and streams of New Jersey. 
That they are restricted to that locality, however, is not probable. 
Physomonas vestita, sp. nov. 
Body subglobose, the anterior truncation obsolete; the entire 
surface clothed with a thin, mucilaginous, finely granular in- 
vestment , through which penetrate numerous delicate, flexible, 
tay-like bodies apparently adherent to-all points of the surface ; 
endoplasm granular ; long flagellum flexible, the distal extrem- 
ity arcuatel y curved, twice the diameter of the body in length,: 
the secondary one one-fourth that length, and vibratile; pedicle 
liform, flexible, four times the diameter of the body in 
length ; contractile vesicles two, sitaated close to and slightly in 
advance of the median line; a linear, slightly curved band or 
stoove near the frontal margin of the body. Diameter of the 
Z00id +4/s¢ inch. Habitat—Pond-water, with Myriophyllum. 
Solitary, 
In two particulars this species differs from the hitherto single 
known member of the genus:—in the absence of the truncate 
anterior border, and in presence ofa linear, dark-bordered band
