face and perhaps also a slight incurvation of the bill. The 

 more plain lemon-yellow color of the under surface of the 

 wing as well as the entirely yellow outer two pairs of tail- 

 feathers I would rather believe to be an individual case of 

 xanthism , which latter seems to be rather common in !the 

 preceding species and which , therefore , will very likely be 

 found in this present species as well. 



3. Tatare luscinia Q. & G. 

 Acrocephalus mariannae, Tristr. Ibis 1883, p. 45, 

 Tatare mariannae, Sharpe, Cat. Birds Br. Mus. VII, p. 528. 



General character: Upper surface olivaceous brown , 

 more fulvous on rump and upper tail-coverts, wings and 

 tail earthy brown, both slightly tipped with fulvous, a 

 superciliary stripe, beginniug at the nostrils, under wing- 

 coverts and edge of wing as well as the whole lower sur- 

 face of the body , except the brown thighs and flanks , 

 pale yellow. Bill slender, very sensibly incurved, upper 

 mandible pale brown , lower whitish , feet brown. 



Wing 3.3; tail 3.0; culmen 1.4. 



One specimen from Guam , Marianne Islands. 



It might be of some value to say, perhaps, that all the 

 three above mentioned species have the tail waved with 

 narrow dark cross-bands when seen under certain lights, 

 and these wavings are by no means stronger in T. luscinia 

 than they are in the two preceding species , so that a 

 division of the genus Tatare into a group with the tail un- 

 handed and another with banded tail, as it is made by 

 Mr. Sharpe in his key to the species of the genus Tatare, 

 is rather inconveniant. 



Having united the species of Tatare to the genus Acro- 

 cephalus , to which they certainly are very closely allied, 

 Mr. Tristram was obliged to give the present species another 

 name. As long, however, as the genus Tatare will be 

 kept separate , and I hope it will , there is no reason 

 whatever to alter the name of T. luscinia into T. mariannae.
