Hudson udgav The Rôti fera or ivheel 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 H u d s o n - 

 Gosses System aldrig kunde blive brugbart, netop maa søges i 

 Opstillingen af disse 7 Typer. Disse Typer ere følgende: 



1. Malleate: Mallei stout; manuhria and unci of nearly equal 



length ; unci 5- to 7 -toothed ; fulcrum short ; as in Brachi- 

 onus urceolaris. 



2. Sub-ma!leate : Mallei slender; manubria about twice as long 



as the unci; unci 3- to 5-toothed; as in Euchlanis deflexa. 



3. Forcipate : Mallei rod-like ; manubria and fulcrum long, unci 



pointed or evanescent; rami much developed and used as 

 a forceps; as in Diglena forcipata. 



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 slender; 



as in Stephanoceros Eichhornii. 



6. Ramate: Rami sub-quadratic; each crossed by two or three 



teeth ; manubria evanescent ; fulcrum rudimentary ; as in 

 Philodina roseola. 



7. Malleo-rarnate : Mallei fastened by unçi to rami; manubria 3 



loops soldered to the unci ; unci 3-toothed ; rami large 

 icith many strice parallel to the teeth; fulcrum slender; 

 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 blevne 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
