This treatise, written in Magyar, and published by the Hungarian 
Academy of Sciences, discusses the structure and affinities of the Hun- 
garian species, accompanied by 47 figures of the more salient forms, with 
anatomical detail. Five genera of Flosculariinm, 4 of Philodincua^ 7 of 
Hydatinceay 8 of Longinetcdy 3 of Scaridinay and 12 of Loricatay are par- 
ticularized {Notommatay Ehr., being renamed Monommatay p. 36). The 
following species are described as new : — Floscularia longilohatay pp. 24 
& 52, pi. ii. fig. 14 ; Rotifer maximus and R. motacillay pi. iv. fig. 34, 
pp. 27 & 52 ; AscomorpTia saltanSy pp. 42 & 52, pi. ii. fig. 17 (also in 
Wiirtemberg); Euchlanis pannonicay pp. 45 & 52, pi. iii. fig. 28 ; and 
Brachionus minimuSy pp. 49 & 52, pi. i. figs. 7 & 8.

Greeff (37) describes the structure of the dermo-muscular tube and 
subjacent muscles, the central nervous and blood-vascular systems (the 
latter is open to the coelom at the tip of the proboscis) ; and the genera- 
tive organs, the number of which is not constant. The ova of Bonellia 
viridis appear to escape into the coelom. The statement of Kowalow- 
sky that l'urhellaria-\\\:.Q> forms of the male sex only are to bo found in 
the uterus of the females of B. viridis is confirmed (as yet only females 
of this species had been observed), but he considers that further obser- 
vations are required. The results of Schmarda on development are 
disputed, while those of Salensky are, in part, confirmed ; the author’s 
own observations on Echiurus pallasi have not been very successful. 
The author does not think that either the history of development, or 
the details of adult structure, point to any relationship between the 
Echiuri and Echinodermay and he is of opinion that the tubes with 
ciliated infundibula resemble more closely the segmental organs” of 
Annelids than the “lungs” of the Holothuroida. 
Ludwig, Z. ges. Naturw. 1. pp. 493-494, describes briefly and figures 
the spectrum of the colouring matter of Bonellia viridis, in which he 
finds five absorption bands.
