But I do not jet wish to express any opinion rc^^ardin;^ 

 the rehitionsliip of those i[;rouj)3 to each other or to any other 

 section of the AvicuhiriiihTi. 



Turning now to the 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 grou[)cd as 

 follows : — 



1. OaxiTnorTnNin.K. — Ona'/hocfttmts, Voc, Meigui ; Omothymus, Tho- 



rell, PinaiiiT ; Phonniiif/ochilus, uov., Borneo; Citharof/nathus, 

 nov., Ikirut'O ; Melopwus, \\u\. { = Selvnocosmia, Simon, in part), 

 JSiaiu. 



2. Selk.nocosmiid.t:. — Ila/ihclasfus, Sim., S. India ; Pacilof/ieria, Sim., 



S. India, Ceylon ; t'liilohradtys, Karsch, S. India, Ceylon ; Mxsa- 

 t/ett's, nov., Biunia to Mergui (":' Pldoyius of Simon and Thoi'ell, 

 in part); Li/ro(/}itithii.s, nov., A,s.<ani; Corcmiocnemis, Simon, 

 I'inanp ; &'/cii(iti//ius, nov., Qneensland ; 'Sele/icco-smia, Au.--s.,Java 

 \c. ; PhliMjuts, Simon, Austro-.Malaya ; Piu/mopoetcs, nov., East 

 Indies. 



These two families are based mainly upon the presence 

 of the stridulating-organs that they possess between the outer 

 surface of the 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 Selenocosmiida3, with the single exception 

 of JIaptoc/astitSj where the club-sliaped rods are wanting ; 

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

 * Natural iScience ' for January 1895 fj is found with but little 

 structural variation in all the genera of Ornithoctonidaj. Of 

 course 1 have not been able to establish tiie 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 JJapIojjelma, Lai/ipropeliaa, Ci/riopagopus^ and 



* Mtms. Simon appears to me to have fallen into error over tlie deter- 

 Uiiiiation of soma of these {renera. For instance, the type of Phoiietjusa 

 is not Greoji of Karscli, iw he states, but belniuUuia of Karsch (<•/". lierl. 

 enl. Zeitschr. 18.S4, p. 348), because this was the only .species referred U) 

 the fjenus when tlie latter was tirst estaWished. Ji.it suice, according to 

 Simon, belandaun is c<jngeneric with his sjiecies aiitilope, which is the 

 tyjHj of JlurjuLiotfieria, it necessarily follows that /Iar/iit.i'i(/teria is syno- 

 nymous with I fionei/n.t(i. 'I'liis lea^es the so-calh'il genus of which Greefi 

 of Karsch is the type without a name. I hesitate, however, to supply 

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

 ticems lo indicate that ^r'/r^t is congeneric with the type of Jli/.ttin/cratcs, 



t " Musical Boxes in Spiders.'' Fig. i) of this pajier siiouid have been 

 described as a Mimayetfif, and not as a I'/ujiiiii/ii/uc/iitui.
