pital process and the basal bone of the dorsal spine are exposed 

 and finely granular*. Occipital process narrow, four times as 

 long as broad ; basal bone of the dorsal spine elongate, trian- 

 gular, two thirds as long as the occipital process, from which 

 it is separated by an interspace. Body much elongate, its 

 depth being one eighth of the total length (without caudal), 

 the length of the head being one fifth. Snout depressed, 

 obtuse, rather broad, twice as long as the eye, which is of 

 moderate size, one seventh of the length of the head. Mouth 

 inferior, as wide as the broad snout. Teeth on the palate in 

 an uninterrupted crescentic band, which is not much narrower 

 than that of the intermaxillaries. Barbels very short and thin, 

 the nasal filaments extending not beyond, and those of the 

 maxillaries but little behind, the orbit ; chin-barbels still 

 shorter. Dorsal spine not serrated, at least as high as the 

 body ; pectoral spine stronger, strongly denticulated interiorly. 

 Adipose fin at least as long as anal. Caudal rounded. Uni- 

 formly dark-coloured. 



One specimen, 10^ inches long.

The outer wall of the air-bladder is thicker than I have seen 

 it in any other fish ; it is comparatively thicker in old ex- 

 amples (20 to 24 inchen) than in younger ones. 



31. Macrones (Liocassis) tamiatus, sp. n. 



D. 1/6. A. 18. 



Head nearly entirely covered with a thin skin above ; but a 

 portion of the occipital process and basal bone of the dorsal 

 spine is exposed and finely granular. Occipital process short, 

 not longer than, and separated by an interspace from, the tri- 

 angular basal bone of the dorsal spine. Body rather elongate, 

 its depth being one sixth of the total length (without caudal) ; 

 the length of the head is one fifth. Snout depressed, broad, 

 obtuse, twice as long as the eye, which is rather small, one 

 sixth of the length of the head. Mouth anterior, the upper 

 jaw being but little longer than the lower. Teeth on the 

 palate in an uninterrupted crescentic band, which is rather 

 narrower than that of the intermaxillaries. The nasal barbels 

 extend somewhat behind the eye, those of the maxillaries to 

 the gill-opening ; and the chin-barbels are about half as long as 



* Thus offering additional evidence of the trivial nature of the genus 

 a Pelteobagrus"
