Femiud. — Cephalothorax ieqnc latus atque longus, c:a 1- 3 niillim., in lateribus fortissime et aniplis- 

 sime rotundatus, parte cephalica parva, impressionibus fortibns limitata; a latere visus dorso inter partem ccplia- 

 licam et tlioracieam fortiter irapresso, posleriora versus arciiato-elevato; jjilis lon^iioiibus fere erectis sat densis 

 sparsus, fiavo-testaceus, vitta media longitudinali nigricanti, quic linea ail)a geminatur, Ii:ic vitta a parte ceplialic-a 

 posteriora versus extensa, interdum parum expressa. Clypei altitudo mandibularum longitudiue fere duplo major. 

 Sternuin cum labio coalito triangulo flavo-testaceum, interdum linea tenui tusoa marginatum, sparsini pilosum, 

 inerme. Oculi 4 antcriores seriem rectam formant; tres utrinque sub-aequales et contiugentes; medii antici parvi, 

 iuter se proximi, a lateralibus anticis spatio remoti quod horura diaraetro pauUo minus est. Mandibulce cylin- 

 drato-ovatae, tibiis anticis non erassiores, latitudine basali paullo plus duplo longiores, testaeeae, pilosae, apice 

 intus dente sat forti armato; unguis minutus, debilis. Jfa.inllce angustpe, rectie, in labium fortiter inclinata>. 

 Palpi breves, teuues, pilosi, parte tarsali sub-cylindrata. Pedes longissimi, pilosi et pubeseentes, flavo-testacei 

 fere toti, femoribus basi et patcllis interdum paullo infuscatis. Pedum prop. 1, 4, 2, 3, l:mi paris 31, 2:di 

 23, 3:tii 17V2> 'iiti 24 millim. longi (in exemplo cujus ceplialotborax 1-3 millim. longus est). Abdomen in- 

 verse sub-ovatum, in dorso sat alte convexum, subter fere rectum, c:a 4 millim. longum et 3' ., millim. latum, 

 cum mamillis ciaereo-testaceura totum, tenuiter pubescens; area vulvce sat niagna, fere in connm obtusum elevata, 

 antice linea recurva nigricanti limitata; vulva ex scuto sat magno, piano, sub-triangulo, nitido, ferrugineo, apice 

 anteriora versus directo, impressionibus duabus longitudinalibus parallelis parum profundis notato constat. 



Mas. — Cephalotliorax, sterniim, labium et majnllce ut in femina, eo cxcepto, quod ceplialotborax paullo 

 latior quam longior est (circa \^|^ miliim. latus, paullo plus I*/, millira. longus). parte cephalica magis elevata 

 et pilosa. Mandibuhv minores quam in femina, ad ipsam basiu dorsi, extus, dente obtuso et magis intus ibidem 

 tuberculo parvo instructse, versus apicem vero, intus, dente sat forti nigricanti armatse (praeter dente in apice 

 intus). Palpi testacei; pars trochanteralis spina maxima curvata obtusa testacea in latere exteriore arraata est; 

 pars femoralis, basi angusta, dente crasso retro directo testaceo fere in medio subter instructa; pars patellaris 



') The palpi of the male Pliolci appear to me to be of a verv remarkable type, and to differ much niore 

 than those of Scytodes, f. inst., from the palpi of spiders in general. In most Pholcinre in fact the buibus 

 genitalis is not fixed on the under side of the tarsal joint, but articulates with its apex, in the same 

 raanner as the joints of the legs and palpi in general are uuited with each other. — The Territelaria:, 

 Filislatoidw, Dysderoidce and Scytodoidoe are not the only spiders, in which the tarsal joint does not cover 

 the l)ulbus: this is also the case with Nephila, and in this genus the bnlbus is also extremely simple and 

 drawu out into a fine |!oint, as in most Territelaria' and in Scytodes. The vulva is in Tetrayiiatha e.rtejisa, 

 f. inst., (and probai)ly also in several other Orbitelariit; and lletitelariie) destitute of horny parts, and quite 

 as simple an in the Territelariiu, Filistatoidae, Dysderoidae and Scytodoidtt. — In Arbanitis (Pholenon) 

 loiiyipes L. KocH (Die Arachn. Austral., p. 472, Tab. XXXVI, fig. 3 — 3 c), of the family Theraphosoidie, 

 the buibus appears to be fixed to the tarsal joint somewhat in the same way as in Pholcus.
