and South India are smaller than those from Borneo. At present, however, I can 

 only separate the Javan form with satisfaction. I name it in honour of Herr Ernst 

 Prillwitz. Type from Mount GeJeh, Java, E. Prillwitz coll. 



With regard to typical Arachnothera a/finis, it may be mentioned that it occurs 

 in Java only, while in the Malay Peninsula it is replaced by ^1. ajfinis modesta, and 

 in Borneo by A. aflinis eceretti. 



6. Arachnothera robusta uropygialis Gray. 



There is also a constant local differentiation in .1. robusta. Examples from 

 Borneo and Sumatra are much brighter below, the abdomen being of a brighter 

 yellow, the foreneck and chest more green, while the latter have a greyish tinge in 

 those from Java. The bill is much longer in birds from Borneo and Sumatra, being 

 about 55 mm. in birds from Borneo, about 43 mm. in Javan birds. 



Gray's name uroju/qialis is available for the Java form, as his plate distinctly 

 shows the greyish tinge on the foreneck ; and, besides, Mr. Walter Rotlischild and 

 I have examined the type of uropi/pialis in the British Museum, and there is no 

 doubt that it is the Java form. 



The Java bird must thus be called Arachnothera robusta uropygialis. 



7. Dicaeum sollicitans sp. nov. 



In the first little sample-collection made for us by Mr. Prillwitz on Mount 

 Gedeh between October 1897 and January 1898, at elevations of from 3000 to 

 5000 feet, there was a small Dicaeum, which caused me not a small amount of 

 trouble. It is not se.xed. It is therefore not imjiossible, as Mr. Rothschild pointed 

 out to me, especially after having examined Dicaeum pijqmaeum from the Philipjiines, 

 that our specimen is \h^ female of some species with a bright-coloured male. It is, 

 however, certainly not the female of any of the known Javanese Dicaei, and I am 

 inclined to think that it belongs to the plain-coloured group comprising iJicaeam 

 concolor, olicaceum,virescens, and en/t//ror/iyHc/ium,iii which the sexes are similar in 

 colouriition. It does, however, uot fully agree with either of them, as one might 

 expect from its new locality. From IK erythrorhijnchum it differs at a glance in its 

 black liill. D. concolor is considerably larger. D. oliraceum and D. rirescens are 

 nearest. Of these the latter (^1). viresce/is) is more greenish above, more yellowish 

 on the abdomen, and darker on the lores. Thus D. oliraceum, which ranges from 

 Nepal, Sikkim and Bhutan through the Assamese hill regions to Tenasserim, 

 Malacca and Sumatra, remains as the nearest ally. From this form, D. olivaceum 

 (I), inornatum of the Catalogue of Birds X. p. 45), the Java bird differs in having a 

 large, more defined and distinct bull' patch on the lores, filling the space from the 

 bill to the eye, in having the bill slightly wider at base and perhaps in a somewhat 

 shorter wing, the specimens of D. olicaceum which I measured having the wing 

 45 to 47 mm., the Java bird only 445 mm. 



It is most desirable to obtain a series of this bird from Java to establisji its 

 validity, but I believe it w'\\\ eventually be a subspecies of D. oliraceum. 



8. Pitta cucuUata Hartl. 



Tliis Pitta is known to extend from India to the Malay Peninsula and Hangka. 

 Mr. Prillwitz sent us a skin labelled as follows: " Djampang, Java 1501) Fuss. 

 Marz 1898. Geschlecht nicht siclier. Fiisse gran. Schnabel schwarz. Name der 

 eingeboreuen Kukup."
