pleuritis endotheliomatosa, but probably had its headquarters in the 
tumour tissue, since many of those found even in the fresh fluid were 
already dead or apparently dying. Its nearest allies are probably 
A. villosa Wallich and A.Jluida Gruber. 
Monograph of Craspedomonads.* — Herr Raoul H. France has done 
good service in monographing this interesting family (Biitschli’s 
Choanoflagellata). He divides it into two sub-families, Codonosiginae, 
including Monosiga , Codonosigci , Codonocladium, Asterosiga, Sphserceca, 
Codonodesmus , Protospongia , and Biplosiga ; and Salpingoecinae, including 
Salpingceca , Lagencecci , Polyoeca , and Biplosigopsis. 
The affinities are thus expressed : — 
Dcndromonadinese 
Anthophysa 
Bcndromonas 
CcpJialothamnium 
Codonosiga 
Codonocladium 
Craspedcmonadincte 
Salpingoeca 
Bicosoeca 
Bikcecineao 
Coccidian of Frog’s Blood-coi puscies.f — Dr. E. Giglio-Tos records 
the occurrence of a Coccidian, whose precise nature remains undeter- 
mined, in those blood-corpuscles which are called “ Spindelzellen ” by 
Recklinghausen, “ hematoblastes” by Hayein, “ piaslrine nucleate ” by 
Bizzozero, and “ Thrombocyten ” by Dekhuyzen. This seems to be the 
first case recorded for these particular elements. 
Stylococcus, a Hew Genus of Flagellat^.J — Under the name Stylo- 
coccus aureus g. et sp. n., Prof. R. Chodat describes an organism found 
in the Lake of Geneva, consisting of a roundish body resembling Chromu- 
lina, with a single immotile cilium several times its own length. It has 
a single golden yellow cliromatophore, and is enclosed in a rounded 
capsule borne on a long stalk. It is reproduced by zoospores. The 
nearest alliance of this organism appears to be with the Chrysomonadinese, 
near to Chrysopyxis, Chrysococcus, and Binobryon. It was found in the 
mucus of a Batrachospermum.
