Bemærkninger. — Denne Familie indeholder 

 knn 2 Slægter, A2)ns og Lepidiiruiy, der staar hin- 

 anden overmaade na'r, og begge har en meget vid 

 geographisk 1'dbredning. idet de er re]n-æsenterede 

 baade i den nye og gande Yerdi-n, ligcsom ogsaa 

 i Aiistralien. Kun den sidste af disse Slægter er 

 repræsenteret i vor Fauna. 



Characters. — Carapaee broadly rounded in 

 I'rout, slightly vaulted and indented behind, with a 

 distinct transver.se cervical furrow defining the head 

 jiosteriorly: the latter shovel-formed and exhibiting 

 a crescent-shaped ventral duplicature, behind wliich 

 the antennae and oral ])arts are situated. Hind jiart 

 of the body jirojecting more or les.s behind the cara- 

 pace, and divided into numerous segments, encircled 

 by tine sjiikes. Caudal lilanu'nts ver_\- much elong- 

 ated. Anterior li]) l>road and Hap-like; posterior lij) 

 bitid. Mandibles with the cutting edge coarsely den- 

 tated. First pair of maxillæ securiform, second pair 

 with a membranous lateral expan.sion. All tlie legs 

 with clearly defined coxal lobes; first pair more or 

 less unlike the remainder, with the endites filiforn.i; 

 the next pairs prehensile, with the endites partially 

 (law-like; 11th pair in tiie female, with the ejnpo- 

 dite and exopodite transformed into a capsular ovi- 

 sac. Males veiy rare, considerably smaller than 

 the fema](\-<, and without special prehensile organs. 



Remarks. Tliis family contains only two 



genera, A})hs and Lepidiiriis, which are very nearly 

 allied, and both have a very wide geographical dis- 

 ti'ilintion, being represented botii in the old and the 

 new world, as also in Australia. Only the latter 

 <d' tliese two genera is represented among the Xrir- 

 w esrian fauna.

Generic Characters. Carapace usually \erv 

 large, covering the -leater part of the body, and 

 furnished jiosteriorly with a more or less marked 

 longitudinal dorsal keel. Last caudal segment ]iro- 

 longed between the caudal filaments to a lanudlar 

 expansion I'^irsl jiaii' of legs with the endites com- 

 parativel\- short and j)rojecting only slightlv be- 

 yond the edge of the cara])ace. There are (i3 pairs 

 of legs. In other respects it agrees with the genus 

 Apii.-: 



Remarks. — The genus iiere treated of was 

 first established b\- the well-known iMiglish natu- 

 ralist. Leach, and is characterised ])riuci]iall\- b\- 

 the ju'esence of a median caudal lanudla. which is 

 altogether absent in Apiis, and by the comparativ(d\- 

 short endites in the first pair of legs. .Vs. however, 

 the species belonging to tiiis genus agree in otiier
