Description. Colonies attached to slender leaves (possibly Vallisneria), showing a typical fredericellid form with narrow tubules and widely spaced zooids; free branches not seen in these specimens. Statoblasts clear and smooth without ornamentation, suture occurring along a rough, finely toothed carina about 10 µm wide; when separated each valve retaining its portion of the carina (Fig. 13 a); dimensions of two statoblasts 350 µm x 195 µm and 365 µm x 165 µm, including carina.

Diagnosis. Statoblasts bear a thin carina extending from each valve around the entire periphery.

Remarks. Specimen ZEV 5022 includes abundant material in good condition, with many small colonies, each bearing several statoblasts. Fredericella carinata n. sp. could be easily mistaken for F. sultana (Blumenbach, 1779) were it not for the carina at the suture. A similar feature occurs in Fredericella sultana crenulata DuBois-Marcus, 1946 (Fig. 13 c), although in that species the two valves are densely pitted, similar to F. indica and F. borealis.

Distribution. The species is known only from its type locality in Odisha State.

Etymology. The specific epithet, meaning “ keeled ” in Latin, refers to the narrow carina encircling the statoblasts at the suture.

Material examined. Holotype: ZEV 5022, collected 3 March, 1908 in the canal at Cuttack, State of Odisha, by Nelson Annandale, originally labeled, “ Fredericella indica. ” On narrow leaves and stems.

Abstract

A review of the phylactolaemate (freshwater) bryozoan collection at the Zoological Survey of India in Kolkata reaches the following conclusions: (1) Fredericella indica Annandale, 1909 from the Indian subcontinent is not the same as the species widely known as F. indica from the northern temperate zones; the latter species name is now changed to Fredericella borealis; (2) Plumatella bigemmis Annandale, 1919 is a junior synonym of Plumatella fungosa Pallas, 1768; (3) Plumatellia persica Annandale, 1919 is a junior synonym of Plumatella casmiana Oka, 1907; (4) Plumatella (Afrindella) testudinicola Annandale, 1912 combines two previously known species: Plumatella bombayensis Annandale, 1908 and Plumatella casmiana Oka, 1907; (5) Rumarcanella minuta (Toriumi, 1941) is a junior synonym of Stolella himalayana Annandale, 1911 which now becomes Rumarcanella himalayana based on statoblast hypertubercles; (6) Plumatella longigemmis Annandale, 1915 and Hyalinella (Australella) indica Annandale, 1915 are both junior synonyms of Hyalinella lendenfeldi (Ridley, 1886); (7) Stolella indica Annandale, 1909, Swarupella andamanensis Rao, 1961 and Swarupella kasetsartensis Wood, 2006, may all be synonymous. The species Plumatella bombayensis is confirmed, and its holotype is re-described. In addition to Fredericella borealis four new species are presented: Plumatella crispa, P. dhritiae, P. paltensis and P. raoi. Validity is rejected for the genera Afrindella, Australella, Stolella, and Swarupella. The genera Rumarcanella and Varunella require refinement and documentation.A taxonomic key to the Indian Phylactolaemata concludes this paper.
