 Transact. ('onn. Acad. Arts & Sinn.,.,. Vol. V. 



Slægtscharaeter. Legemel mere riler mindre smæk- 

 kert, med forholdsvis lange Sidefortsatser. Hovedsegmentet 

 fortil indknebet og fremragende over Roden af Snabelen. 

 Halesegmentet mere eller mindre forlænget. Øieknuden 

 beliggende ved Enden af Pandedelen, vel udviklet eller 

 rudimentær. Snabelen udgaaende fra Hovedsegmentets ven- 

 trale Side. skraat nedadrettet. Saxlemmerne forholdsvis 

 svage, haarbesatte, med Saxen liden og Fingrene neppe 

 forciperede. De falske Pødder ho- Hannen 6-leddedé, 

 sidste Led meget lidet, børstebesat, uden Klo. Gangfød- 

 derne spinkle, mere eller mindre forlængede, sparsomt 

 haarbesatte, Tarsalleddei meget kort. Fodleddet forlænget, 

 med Inderkanten fremspringende ved Basis og her bevæb- 

 net med stærke Torner. Endekloen stærkt forhenget, lefor- 

 mig, Bikløerne yderst smaa og rudimentære, ikke fremra- 

 gende foran Endekloens Yderkant. Flere kugleformige 

 Ægmasser festede til de falske Pødder hos Hannen. 



Bemærkninger. Den Character, hvorpaa Wilson 

 væsentlig synes at have grundet denne Slægt, nemlig den 

 formentlig!' Mangel af Bikløer, er vistnok ubrugelig, da 

 saadanne i Virkeligheden foréfindes, skjøndt i en megel 

 rudimentær Tilstand: men jeg tror dog. at Slægten bør 

 opretholdes, da de herhen horende Arter viser en Del 

 andre eiendommelige Characterer, der synes at maatte 

 kunne tillægges generisk Betydning, saasom Hovedsegmen- 

 tets characteristiske Form. Saxlemmernes svagere Bygning, 

 og navnlig det større Antal Led i de falske Fødder. 

 Slægten synes at tadle ikke faa Arter. Foruden den typi- 

 ske Form. .4. Initu? Wilson, og de to nedenfor nærmere 

 •beskrevne Arter, horer herhen Phoxichilidiwm virescens 

 Hodge, samt efter al Sandsynlighed de 2 af Dohrn be- 

 skrevne middelhavske Arter, P. angulatwm og exiguum. 

 Endelig synes den af Hoek fra Ohallenger Expeditionen 

 opforte Art P. insigne, ialfald at dømme efter de falske 

 Pødders Udseende, nærmest at maatte henregnes til samme 

 Slægt.

Generic Character. Body mon- or less slender, with 

 comparatively Long lateral processes. Cephalic segment 

 anteriorly constricted and projecting beyond hase of pro- 

 boscis. Caudal segmenl more or less elongate. Oculifer- 

 ous tubercle located al extremity of frontal part, well-deve- 

 loped or rudimentary. Proboscis issuing from ventral side 

 of cephalic segment, directed obliquely downwards. Cheli- 

 fori comparatively feeble, covered with Hair, having the 

 cliela small and the fingers scarcely forcipate. False legs 

 in the male 6-jointed, terminal joint very small, bristle- 

 bearing, without any claw. Ambulatory legs slender. more 

 or less elongate. sparingly hair-beset, tarsal joint very short, 

 propodal joint produced, with inner margin projecting at 

 base, aud armed there with strong spines, terminal claw 

 elongate, falciform, auxiliary claws exceedingly small and 

 rudimentary. not projecting beyond outer margin of ter- 

 minal claw. Several gloliular egg-niasses attached to the 

 false legs in the male. 



Remarks. — The character on which Wilson would 

 seem to have chiefly founded this species, viz.. its supposed 

 want of auxiliary claws. is certainly untenable, as such do 

 really occur, although in a very rudimentary state; meanwhile 

 the genus should, I cannot hut think. be retained, as the 

 species classed under it exhibit certain other peculiar 

 charåcters, to which apparently we can assign generic 

 value, thus, for example, the characteristic form of the 

 cephabc segment, the feebler structure of the chelifori, and 

 more especially the greater number of joints in the false 

 legs. The genus would appear to comprise not a few 

 species. Excluding the typical form. A. Jentits. Wilson, 

 and the 2 species described below, it counts Phoxichilidium 

 virescens, Hodge, and in all probability the 2 Mediterranean 

 species, P. angulatwm and exiguum, described by Dohrn. 

 Finally, the species etablished by Hoek from the „Ohal- 

 lenger" Expedition, 1'. insigne, judging at least by the ap- 

 pearance of the false legs. would appear to approximate 

 the same genus closest.
