ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 455 



Parasites in Roumania.* — N. Leon gives a list of the animal para- 

 sites which he has to deal with in his laboratory at Iassy. He notes 

 Entamoeba biiccalis, Spirochseta buccalis, and other Protozoa ; Dicro- 

 cmlium lanccolatum in the bile-ducts of sheep and cattle, often along 

 with Distomum hepaticum ; Sarcophaga wohlfahrti in a child's ear and 

 numerous other insects ; the Acarids Dermacentor reticulatus and Rhipi- 

 cephalus expositicius on sheep ; o20 specimens of Ascaris lumbricoides 

 passed from a woman in six weeks ; and among Cestodes some interesting 

 forms, e.g. Diplogonoporits brauni and Braunia yassyensis. 



Tunicata. 



New Species of Didemnoides.t — G. Daumezon describes Didem- 

 noides massiliense sp. n., which is interesting in occupying an inter- 

 mediate position between Diplosomidae without spicules and Didenmidfe 

 with perfect spicules. He found two forms together on the same support : 

 (1) a black form with all the ectoderm pigmented, but with unpigmented 

 embryos ; and (2) a clear yellow form with unpigmented thoracic ecto- 

 derm and slightly pigmented visceral ectoderm, and with red embryos. 



New Species of Pyrosoma4 — G. Neumann describes P. triangulum 

 sp. n., captured by the ' Valdivia ' off Somaliland. The surface of the 

 mantle was covered by lancet-like processes, resembling the appearance 

 of P. giganteum. The individual animals are irregularly crowded to- 

 gether. The greatly arched dorsal surface and the much curved endo- 

 style rising up posteriorly give the branchial sac a peculiar rounded 

 triangular appearance. 



Neumann § describes another new species, P. ovatum, from the South 

 Atlantic. The form of the colony is unique in being oval or almost 

 spherical. Here and there very long oesophageal tubes protrude from 

 the surface. The epithelial lining of the oesophageal tube has large 

 stellate pigment-cells, which are not represented in any other species. 



New Species of Doliolum.|| — G. Neumann describes D. resistibile 

 sp. n. from between 64° 2 'J' and 65° 32' S. in the pack-ice region. It 

 belongs to the sub-genus Dolivlina, and has its nearest relative in 

 D. intermedium, from which it is separated by the short endostyle and 

 by the dorsal and ventral attachment of the branchia at the fourth 

 muscle-band. 



INVERTEBRATA. 



Mollusca. 



a. Cephalopoda. 



Tentacular Apparatus of Cephalopods.il — J. Guerin gives a detailed 

 account of (1) the skin and its varied structure at different places ; 

 (2) the extremely complex musculature (brachial, acetabular, acetabulo-
