 Boopsetta umbrarum, Alcock, Journ. As. Soc. Bengal, vol. lxv. pt. 2,

Fishes, pi. xvii. fig. 5. 



A series of specimens lately dredged from off the Anda- 

 nians, 185 fath., shows that the fish I described as Boopsetta 

 umbrarum is the adult of a fish that I had previously described 

 as Poecilopsetta prcelonga. 



This certainly differs from P. colorata, Gunther, and from 

 P. maculosa, mihi, not only in the form of the body, but in 

 the relations of the eyes, which are larger and are in close 

 contact, the upper one bulging far more into the dorsal profile. 

 I do not, however, think that the differences are sufficient to 

 justify their generic dissociation. 



XXIII. — On new Species o/'Histeiidae and Notices of others. 

 By G. Lewis, F.L.S. 



Last year two papers on Histeridse appeared in this Magazine, 

 one in August, the other in October ; these papers included 

 34 new species, the greater part of which were of African 

 origin. The present memoir treats of 14 African, 11 from 

 the New World, and 2 Asian new species. Of the African 

 species Mr. Guy A. K. Marshall has again contributed some 

 which are very interesting, notably Pachycrccrus princeps and 

 Pelorurus carinatus, and I am again much indebted to him 

 for giving me extracts from his journal which record the 

 habits and indicate the situations where his captures were 

 found. 



The Saprinus I describe is a very remarkable and pretty 

 species ; it has been found by Mr. L. Peringuey in the 

 mounds of refuse formed outside the galleries of termites. 

 The termites bring out from their burrows vegetal and other 

 matter which are undesirable within the precincts of their 

 colony, and these as they accumulate set up fermentation and 

 attract stercoraceous and other species on which the Saprinus 

 as an insectivorous species apparently feeds. The Saprinus 

 is similar to several Indian species, S. elegantulus ) Mars.,
