DR. RICHARDSON'S DESCRIPTION OF AUSTRALIAN FISH. 127 



to the upper pharyngeal cushions, and their small longitudinal, mesial keel of smooth 

 integument fits into the division between the latter. The first branchial arch bears an 

 exterior row of compressed, subulate, and acute rakers. The inner row of that arch, 

 and both rows of the other arches, consist of short, compressed, triangular processes, 

 which are toothed interiorly. 



The stomach of the individual that was examined was lined with coagulated mucus, 

 which exhibited no remains of any organized body when examined under the micro- 

 scope.
