In 1885 Carus gave the following diagnosis: 



"Antennae longte; mandibular palpo triarticulato; segmentum I. thoracale cum secundo 

 coalitum; par pedum V. manu prehensili cheliformi, articulo basali laminar! amplo; par VII. 

 gracile exungue; stili caudales lamellosi.» 



In 1886 Gerstaecker characterized the genus with following words: 



»Kopf ausserst plump, oval abgerundet, weiter nacb unten als der Mittelleib herabreichend. 

 An diesem die beiden vordersten Segmente stark verki'irzt oder selbst verschmolzen, das fiinfte 

 am langsten, die beiden letzten nach unten und hinten ausgezogen. Die beiden vurderen Bein- 

 paare verkiirzt, mit scharfer Endklaue, das dritte und vierte verlangert, mit erweitertem und 

 fingerformig ausgezogenem drittletzten Gliede, das fiinfte mit grossem, sehildformigem Schenkel- 

 gliede (unter welchem das sechste Paar tbeilweise versteckt liegt) und sehr breiter, am Innen- 

 rande gezahnter Greifhand, °"e«;en Avelche sicb die zwei<>'liedriy;e Endklaue in der Richtung- nach 

 vorn hin einschlagt. Audi das sechste und siebente Paar unit sehildformigem Schenkelgliede, 

 aber ohne Greifhand. Am Hinterleib die vier Endsegmente stark verki'irzt, zusammen kaum 

 langer als jedes der drei grossen Basalsegmente.» 



The first instituted species of the genus were Anchylomera Blossevillei and A. 

 Hunteri, proposed in 1830 by H. Milne Edwards. 



The next was Hieraconyx abbreviatus n. sp., described in 1836 by Guerin Meneville; 

 it is a synonym for Anchylomera Blossevillei. 



In 1850 de Natale described Cheiroprestis messanensis, which also is synonymous 

 with A. Blossevillei. 



In 1852 Dana proposed the two new species Anchylomera jjurpurea and A. t/iyro- 

 poda, the former of which is the male, and the latter the female of A. Blossevillei. 



In 1862 Spence Bate instituted the new species A. antipodes, describing and de- 

 lineating the male and female form. Even this specific name is, in my opinion, a syno- 

 nym for A. Blossevillei. 



Thus we have to record only two species, viz. A. Blossevillei and A= Hunteri, 

 the latter of which is somewhat dubious, and not actually examined since it was described 

 by H. Milne Edwards. 



The sexual dimorphismus is shown only in the form of the first pair of antenme 

 and in the female wanting the second pair of antennae and the mandibular pal]). 



The two species are distinguished as shown in this table: 



A. The head is large and much deeper than the person. The first pair of peraso- 



poda are much shorter than the second. The foremost tooth on the under 

 margin of the carpus, or the carpal process, in the fifth pair does not reach 

 deeper than the following teeth; the dactylus of the same pair is long. _. I. A. Blossevillei. 



B. The head is comparatively small and not deeper than the person. The first 



pair of perajopoda are almost as long as the second. The foremost tooth on 

 the under margin of the carpus, or the carpal process, in the fifth pair reaches 

 much deeper than the following teeth. The dactylus of the same pair is 

 very short 2. A. Hunteri.
