Hudson udgav The Rotifera or wheel animalcules, baserede de det 
deri givne nye System for en stor Del paa Munddelenes Bygning og 
opstillede 7 forskellige Typer, der alle skarpt skulde kunne sondres fra 
hverandre; vi skulle se, at en af Aarsagerne til, at Hudson- 
Gosses System aldrig kunde blive brugbart, netop maa søges i 
Opstillingen af disse 7 Typer. Disse Typer ere følgende: 
1. Malleate: Mallei stout ; manubria and und of nearly equal 
length ; und O- to 7-toothed ; fulcrum short ; as in Brachi- 
onus urceolaris. 
2. Sub-malleate: Mallei siender ; manubria about tidce as long 
as the unci ; und 3- to 5-to o thed ; as in Euchlanis deflexa. 
3. Forcipate: Mallei rod-like ; manubria and fulcrum long , und 
pointed or evanescent ; rarni mucli developed and used as 
a forceps ; as in Diglena fordpata. 
4. Incudate: Mallei evanescent ; rami highly developed into a curved 
forceps ; fulcrum stout ; as in Asplanchna Ebbesbornii. 
5. Uncinate : Unci 2 toothed ; manubria evanescent ; incus siender ; 
as in Stephanoceros Eichhornii. 
6. Ramate: Rami sub-quadratic\ eacli crossed by two or three 
teeth ; manubria evanescent ; fulcrum rudimentary ; as in 
Philodina roseola. 
7. Malleo-ramate: Mallei fastened by unci to rami ; manubria 3 
loops solder ed to the unci ; unci 3-toothed ; rami large 
with many strice parallel to the teeth ; fulcrum siender ; 
as in Melicerta ringens. 
Under de forcipate Munddele omtale Hudson-Gosse i en 
Anmærkning endnu en Art af Munddele, de saakaldte virgate, som 
de anse for en Varietet af de forcipate og karakterisere saaledes: 
the rami as well as the mallei rod-like ; and the whole apparatus 
looks like one forceps within another. 
Disse 7 Typer af Munddele ere bievne akcepterede i alle følgende 
Forfatteres Arbejder, og alle hidtil undersøgte Munddele har man ment 
at kunne henføre til en af disse Typer; herfra maa dog undtages
