554 Mr. W. L. Distant on 



Snout blunt, scarcely projecting beyond mouth ; nasal barbel, 

 when laid back, extending- to posterior edge of eye ; outer 

 mandibulary barbel much longer than inner, but shorter than 

 maxillary barbel, which just reaches operculum. Teeth on 

 palate in a curved band, which is narrowest in the middle. 

 Dorsal I 7 ; spine not or but feebly serrated, ^ length of 

 head ; adipose fin longer than its distance from dor.^al. 

 Anal 18-20. Pectoral spine serrated, g lenath of head ; 

 clavicular process extending beyond its middle. Pelvics 

 nearly or quite reaching anal. Caudal slightly emarginate 

 or truncate. Caudal peduncle 1| to If as long as deep. 

 Brownish, with traces of longitudinally expanded pale areas; 

 fins with dusky margins. 



Five specimens, 75 to 130 mm. in total length, from Kia- 

 tiang-fu. 



In the largest specimen there is an interspace between the 

 occipital process and the basal bone of the dorsal spine, but it 

 evidently belongs to the same species as the others. L. tcenia- 

 tus, Giinth., differs in the smaller head, broader and rugose 

 occipital process, and the more slender caudal peduncle. 



LXVI. — On a small Collection of Rhynchota made hj 

 Mr. David R. Tail at Henderson's Island. By W. L. 

 Distant. 



Henderson's (or, perhaps, as it is better known, Elizabeth) 

 Island is only about five miles in length, and in the remote 

 Pacific region : lat. 24° 21' S. and long. 128° 18' W. The 

 fine species of Gatacanthus here described is probably not 

 endemic, but a migrant from some of the larger and little- 

 known islands in this area. 



The types are in the British Museum.
