1914] Sharp: Diplodinium ecaudatum 47 



a partial description of the process of division in the Ophryoscole- 

 cidae and in Dasytricha. 



Fiorentini (1889) published a short paper dealing mainly with 

 the genera Diplodinium and Entodinium. This paper is profusely 

 illustrated and although the drawings are crude as compared to those 

 of either Schuberg or of Eberlein, they are still, in some respects, more 

 true to life than are those of either of the others. Fiorentini is 

 apparently the first to describe individual species of the genus 

 Diplodinium. He figures and briefly describes nine species (see table 

 below). To the genus Entodinium he adds two new species and to 

 the genus Buetschlia one new species (see table below) . It seems that 

 Fiorentini contented himself with the discovery and naming of new 

 species rather than with the careful and accurate description and 

 illustration of the species upon which he worked. In general his 

 methods were crude and his descriptions too brief. To these we shall 

 refer again. 



It is interesting to note in this connection that Fiorentini (1890) 

 in his paper dealing with the Protozoa parasitic in the intestinal 

 tract of the horse, describes two new species which he refers to the 

 genus Entodinium Stein, i.e., "Entodinium valvatutn" and "Ento- 

 dinium, bipalmatum," and also two new species which he adds to the 

 genus Diplodinium Schuberg, i.e., "Diplodinium uncinatum" and 

 "Diplodinium unifascicidatum." Since, however, the descriptions of 

 these new species are not in accord with the characteristics of the 

 genera Entodinium. and Diplodiniuyn respectively as laid down by 

 Stein (1858, p. 69), and Schuberg (1888, p. 404), and Biitschli 

 (1888, p. 1783), it is evident that Fiorentini made a serious mistake 

 in assigning these species to the genera Entodinium and Diplodinium, 

 a fact which was very clearly pointed out by Bundle (1895, pp. 296- 

 298 and 309-312). In this paper Bundle founds the new genus 

 Cycloposthium to which he assigns Entodinium hipalmatum Fioren- 

 tini, which therefore properly becomes Cycloposthium hipalmatum 

 (Fiorentini) and stands as the type species. In the same paper 

 Bundle (1895) founded another new genus, Blepharocorys, to which 

 he referred both the Entodinium valvatum Fiorentini which then 

 becomes Blepharocorys valvatum (Fiorentini) type species, and also 

 Diplodinium uncinatum Fiorentini which, therefore, becomes Blephar- 

 ocorys uncinatum (Fiorentini). Bundle (1895) does not discuss 

 Diplodinium iinifasciculatum, but it can be seen at a glance that an 

 animal such as Fiorentini has pictured as Diplodinium unifasci-
