and into the dorsal and ventral angles of the free end these 

 two portions of the abdominalis are inserted. The pars 

 posterior fixes itself into the ventral angle, the pars anterior 

 into the dorsal angle. 



In Pityriasis the pars posterior is inserted into the free 

 end of the region of the tract now under discussion, and the 

 pars anterior crosses over this insertion so as to become 

 attached to the postero-internal angle of the tract. 



Latissimus dorsi dorso-cutaneus. — This is exceptionally 

 well developed in Paradisea ; but the same peculiarities 

 which obtain in this genus are met with also in Ptilonorhyn- 

 chus and Sericulus ; in these genera, however, the muscle is 

 but feebly developed. In Manucodia comrii this muscle 

 merges with the cucullaris {pars cranialis) cephalad of the 

 dermo-cleido-dorsalis [cucullaris pars cervicalis) , at the point 

 Avhcre it (pars cranialis) turns downwards to its insertion on 

 the clavicle. 



Summary. 



Though the foregoing detailed descriptions of the pterylosis 

 and dermal myology of the genus Paradisea are more complete 

 than any hitherto published, there are yet several matters 

 to be cleared up ; and still more remains to be done in the 

 case of other genera. 



In so far as Paradisea and its display is concerned, I feel 

 that I have been able to add but little to the interest of 

 Mr. Grant's vivid descriptions. The dissecting-table is not 

 the channel through which phenomena like these can be 

 studied. 



As touching the pterylosis of Paradisea, I would point out 

 the necessity of examining females with a view to ascertaining 

 whether in them the outer branch of the ventral tract is 

 similarly enlarged, and also whether the accessory slip to 

 the muscle attached to this tract is present. 



From what I have seen in the course of the preparation of 

 this paper, I am inclined to believe that the Birds-of- Paradise 

 are by no means so closely related to the Corvidse or to the 

 PtilonorhynchicUe as is generally supposed at the present
