In this Order are nine species of Ascaris, two of Strongylus, six of Spirop- 
tera, nine of Trichosoma, and three of Filaria undetermined by Dr. Belling- 
ham. 
The Irish species given in the preceding catalogue so far outnumber the 
British species known, that the usual comparison is uncalled for. Dr. Belling- 
ham remarks, “ The little attention which these animals have attracted in these 
countries will be apparent from the fact, that in the only works which con- 
tain lists of the British species of Etozoa, viz. Pennant’s British Zoology, 
and Turton’s British Fauna, but twenty-eight are described as indigenous, 
and four of these are noticed twice under different names, leaving but twenty- 
four distinct species; while in the limited opportunity which I have had, I 
have discovered and preserved upwards of 220 species, and several of these 
occurred in six, others in ten, and one species in as many as fifteen different 
animals.” ‘The number of Irish species determined by Dr. Bellingham is 
143*; of species undetermined, but brought under their respective generat, 
eighty :--from the many works consulted, but in vain, for these latter, there is 
little doubt that the greater portion must be undescribed. Dr. Drummond 
too informs me that he has obtained many E/ntozoa which he believes to be 
new. ‘The species recorded by Dr. Bellingham were procured in Dublin ; 
those by Templeton and Dr. Drummond in Belfast. 
* Three species as indicated in a foot note are from British animals. 
+ Dr. Bellingham has some £ntozoa which he cannot refer to any genus, and 
knows of several species having been obtained in Dublin, which are not included in 
his catalogue. 
{ Botriocephalus solidus is an exception, having been found by Dr. G. J. Allman in 
a Gasterosteus aculeatus taken in the co. of €ork—in specimens of this fish captured 
in the neighbourhood of Dublin Dr. Bellingham could never find this Entozoon.
