ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 497 



In another paper * Gineste describes the nuclear apparatus of Tri- 

 chomonas cavise, which inckides a reproductive nucleus, a vegetative 

 semilunar nucleus, and a large blepharoplast which gives origin to two 

 important sub-equal flagella. 



Spirochgete of Earthworm. f— John ^yestray Cropper followed tlie 

 development of " bodies " like " Kurloff's bodies " in some of the epi- 

 thelial cells of the seminal vesicles of the earthworm, and showed that 

 they become free Spiroch^etes. The name Spirochseta lumhrici is 

 suggested. 



Trypanosomes in Mole Flea. J — A. Laveran and G. Franchini 

 report the occurrence of Trypanosoma talpse in the mole flea, Falseop- 

 sylJa gracilis. They describe oval, fusiform, Leptomonad, and Trypano- 

 some-like phases in the flea. The case is analogous with that of Try- 

 panoso7na leivisi in the rat and the rat-flea. 



Parasites of Fishes.§— H. 0. Williamson describes an intracapillary 

 parasite of the haddock {Gadiis seglefinns) which gives rise to the con- 

 dition known as " spotted haddock," " greasers," or " smelly haddock." 

 Its position is uncertain ; . the name Dohis adus is proposed. It often 

 occurs along with the Trematode, Gasterostomum gracilescens. A green 

 parasite from the muscles of Gadus callarias is named Roles trelis. 

 Both these forms are regarded as quite new. Several other forms are 

 reported such as Pleistophora hippoglossoides Bosanquet from the 

 muscles of Anarrfiichas lupus and Zoarces viviparus. 



Dermocystidium pusula (Perez) from the Newt's Skiii.|| — Hans 

 Moral describes an enigmatical parasite, discovered and named in 1907 

 by Perez, which causes minute nodules on the skin of Triton cristatus. 

 It is a unicellular parasite, and includes a puzzling internal body — pro- 

 bably of nutritive significance. But the systematic position of the para- 

 site remains quite uncertain. 



Hsemogregarine of Fer de Lance. If — Madame Phisalix found a 

 Hffimogregarine in various phases in the blood of one of two specimens 

 of the Fer de Lance {Lachesis lanceolatus) fresh from Brazil. She 

 describes " vermiculous " forms within the red-blood corpuscles, " ver- 

 miculous " forms free in the blood, a cyst with two individuals (macro- 

 merozoites), and cysts with granular contents and two to four nuclei.
