Arthrocnodax Occidentalis N. SP. (Dipt.)

Descriptions of Eumonhystera borealis n. sp., Sphaerolaimus occidentalis n. sp., and a Redescription of S. gracilis de Man 1876 (Nemata) from Bothnian Bay, Baltic Sea.

The free-living nematodes Eumonhystera borealis n. sp., Sphaerolaimus occidentalis n. sp., and S. gracilis de Man 1876 from Bothnian Bay in the northern Baltic Sea are described and illustrated. Eumonhystera borealis n. sp. differs from other species by its small body size (314-393 mum), narrow body (a = 37-49), and large anterior amphids. In Sphaerolaimus occidentalis n. sp. the amphids are po...

Notation: In the sequel K is a field and Σn is the group of permutation over n elements. If A is an operad, then the K-vector space of n-ary operations is denoted as usual by A(n). Recall that if A is regular, then A(n) := An⊗KΣn, where An is the K-vector space of n-ary operations without permutations of the entries. We adopt Sweedler notation for binary cooperation ∆ on a K-vector space V and ...

Anuretes grandis sp . n . ,

A new species of caligid copepod (Siphonostomatoida), Anuretes grandis sp. n., parasitic on the painted sweetlips [Diagramma pictum (Thunberg)] in Taiwan is described. The new species is distinguished from its congeners by having: (1) free margin of cephalothorax not covering fourth pediger, (2) large genital complex longer than 2/3 of the cephalic shield, (3) no maxillary whip, (4) leg 3 with ...

Pullulomyxa botrytis n. sp.

A brief note was published some years ago by W. T. Morgan of the Lister Institute, London, and the writer (1932) describing the isolation from decayed woody tissues of a micro-organism which decomposes the specific polysaccharides of Shigella dysenteriae, Shiga; Shigella dysenteriae, Flexner Y; Pneumococcus Type II; and the tubercle bacillus. At the time a study of the relationship of this orga...
