Some account is given in this paper of certain nematodes obtained by Prof. G. E. Gates from the coelomic cavities of various species of earthworms from South India, Assam and Singapore. The material was kindly submitted to the writer by Prof. Gates in 1936, 1937 and 1939. Of the forms included in it several were represented by specimens insufficient or unsatisfactory for adequate description, and it has seemed advisable to deal only with those species of which a reasonably full account can be given. Of these there are seven, all of which are thought to be new. Four of them can be assigned to a known genus, Synoecnema de Magalhães, 1905; the other three probably represent as many new genera.

Coelomic Cavities

A freshwater angelfish ( Pterophyllum scalare) hatchery experienced variable levels of emaciation, poor growth rates, swollen coelomic cavities, anorexia, listlessness, and increased mortality within their fish. Multiple chemotherapeutic trials had been attempted without success. In affected fish, large numbers of protozoa were identified both histologically and ultrastructurally associated with the gastric mucosa. The youngest cohort of parasitized fish was the most severely affected and demonstrated the greatest morbidity and mortality. The protozoa were morphologically most consistent with Cryptosporidium. All of the protozoan life stages were identified ultrastructurally and protozoal genomic DNA was isolated from parasitized tissue viscera and sequenced. Histological, ultrastructural, genetic, and phylogenetic analyses confirmed this protozoal organism to be a novel species of Cryptosporidium.

Rouxicrinus vestitus new genus, new species, collected during submersible dives at depths of 421–887 m near Barbados, Colombia and the Bahamas is described, and notes on ecology are included. It is referred to the family Septocrinidae Mironov, 2000, which now comprises three genera, Zeuctocrinus A.M. Clark, 1973, Septocrinus Mironov, 2000, and Rouxicrinus new genus. This new genus differs significantly from both Septocrinus and Zeuctocrinus in having numerous low columnals in the proxistele, which tapers toward the crown, first pinnule arising more proximally, thorns on brachials and pinnulars, and a thick covering of soft tissue on arms and pinnules.
