c. Haiyactira. 



But I do not yet wish to express any opinion regarding 

 the reLationship of these groups to each other or to any other 

 section of the Aviculariidas. 



Turning now to tlie Oriental forms, we find that they fall 

 into two distinct sections, which I propose, at least provi- 

 sionally, to regard as families. They may be grouped as 

 follows : — 



1. OuNiTHOCTONiD.^. — Ofui/hocfom/s, Poc, Mergui ; Oniothymus, Tho- 



rell, Pinang ; I'honiu'/iyochihcs, nov., Borneo; CitharoynatJius, 

 nov., Borneo ; Melopw us, nov. [ = Sek'nocusmia, Simon, in part), 

 Siam. 



2. Selenocosmiid.t:.— /i«^*/(>c/«*-/?(s, 8im., S. India ; Pwcilotheria, Sim., 



S. India, Ceylon ; Chilohrachys, Karsch, S. India, Ceylon ; Musa- 

 f/C'tes, nov., "Burma to Mergui (? Phloyius of Simon and Thorell, 

 in part); Lyrogmttlnis, nov., A.ssam; Coremiocne}iiis, Simon, 

 Pinang; Selenotypus, nov., Queensland; Selenocosmia, Auss., Java 

 SiC. ; I'hlogius, Simon, Austro-^dalaya ; Psalmupceus, nov.. East 

 Indies. 



These two families are based mainly upon the presence 

 of the stridulating-organs that they possess between the outer 

 surface of tlie mandible and the inner surface of the coxa of the 

 palp. One of these organs, which was briefly described many 

 years ago by Prof. Wood-Mason, is found well developed in 

 all the genera of jSelenocosmiidaj, with the single exception 

 of Jrlaj^loclastus, where the club-shaped rods are wanting ; 

 and the other, which has already been described by myself iu 

 ' Natural Science ' for January 1895 f, is found with but little 

 structural variation in all the genera of Ornithoctonida3. Of 

 course 1 have not been able to establish the presence of either 

 of these organs in genera that are unknown to me; but 

 analogy leads me to suppose that either one or the other will 

 be found in Ilaplopehna, Lampropelma^ Cyriopagopus^ and 



* Mons. Simon appears to me to have fallen into error over the deter- 

 mination of some of these genera. For instance, the type of Phoneyusa 

 is not Greefi of Karsch, as he states, but belanckma of Karsch {cf. Berl. 

 ent. Zeitschr. 1884, p. 348j, because this was the only species referred to 

 the genus when the latter was hrst established. But since, according to 

 Simon, helandana is congeneric with his species anfilope, which is the 

 type of Har pax other iu, it necessarily follows that Flarpuxotheria is syno- 

 nymous with I'lioneyusa. Tliis leaves the so-called genus of which Gi'eefi 

 of Karsch is the type w'ithout a name. I hesitate, however, to supply 

 this apparent deficiency, on the ground that the material at my disposal 

 seems to indicate that Greeji is congeneric with the type of Hysterocrates. 



t " Musical Boxes iu Spiders." Fig. 9 of this paper should have been 

 described as a Mumyetes, and not as a Phonninyochilus.
