Protozoa - Spumellaria - Patulibracchiidae

Discussion

Original description: Rays of medium width, nearly equal in length, having large expanded bulbous tips. Mesh work medium in size with predominance of linearly arranged square pore frames on rays and pentagonal pore frames on ray tips; pore frames without prominent nodes at vertices.

Original remarks: Homoeoparonaella hydensis, n. sp., differs from H. elegans (Pessagno) by having larger, more expanded tips with several short spines, and by possessing larger pore frames on its rays.

Etymology: This species is named for the Hyde Ranch, near its type locality.
