Fig. 1. Part of a colony of Cornularia minuta sp. nov. Actual size. 



2. A partially retracted polyp of Cornularia minuta, showing the 



wrinkled perisarclike covering of the basal portion. Much 

 enlarged. 



3. A cross section of one of the stolons of Cornularia minuta, showing 



the perisarc (a), the endodermal canals (6), and the thick 

 mesogloea. From camera lucida outlines. X 202.5. 



4. Camera lucida outline of an expanded polyp of Cornularia oninuta. 



X23.5. 



5. A schematic representation of a transverse section through a 



retracted polyp of Cornularia minuta to show the relative posi- 

 tions of the body layers, a, the perisarc. The ectoderm is cross- 

 lined, the mesogloea is in black, and the endoderm is represented 

 by a line. ( Siphonoglyphe not indicated.) 



6. A drawing, from camera lucida outlines, of part of an oblique, 



transverse section through a contracted polyp of Cornularia 

 minuta. a, the point of junction of the body cavity and one of 

 the stolons; a', an oblique section through one of the endodermal 

 canals of the stolon; b, the perisarc; c, the wall of the polyp, 

 represented in black; d, the stomodseum; e, the siphonoglyphe; 

 / and /', mesenteries. X 65.5. 



7. An oblique section through the ectoderm of a tentacle of Cornularia 



minuta, showing the ectoderm nuclei and the peculiar bodies 

 found in the ectoderm cells. X 13.40.
