POUDTFUL AND REJECTED GENERA. 61 



Genus TYPHLOTEOCHA, Schmarda (135). 



The only spacies, T. zyijodonta, was found by Solimarda, in standing water, at 

 S. Juan del Norte, Central America ; and was placed by him among the Ilydatincea. 

 It is somewhat like FlosctUar a campanidata. The body is nearly cylindrical ; is sur- 

 mounted in front by a five-lobed funnel-shaped cup, and terminated behind by a long 

 toe-less narrow foot. Schmarda says nothing of the approach to the alimentary canal 

 (so striking a part of the structure of the Floscules), but merely notices that the lobes 

 are closely edged with cilia, of which two are very long. He says that the mastax is 

 a transverse ellipsoid ; and that the ovary stretches down to the bottom of the long foot. 

 It is hardly possible that all these statements should be correct. 



ADDEND A. 



Flosculaeia coeonetta, (var.). Mr. Thos. Whitelegge found, in 1885, in Sydney, 

 N.S.W., a variety of coronetta which had the tips of its lobes, on their inner sides, 

 expanded into flat discs. The figure (PI. XXXIV. fig. 1) I owe to the courtesy of 

 Mr. W. Burue Poole, who found the creature in a small pond in the Botanical Gardens 

 of Adelaide. 



FuECULAEiA GAMMAEi, Plate (209), (PL XXXIV. fig. 8). An ecto-parasite dis- 

 covered by Dr. Plate on the branchial lamina of Gammarus pulex. There is nothing 

 remarkable in its structure except a pair of luiusually long foot-glands.
