title: Further observations on the corpuscles of Stannius in two Indian hill-stream teleosts.
abstract: The corpuscles of Stannius in Glyptothorax pectinopterus and Pseudecheneis sulcatus occur in close proximity to the mesonephros. They are encapsulated structures comprising of secretory cells which make up a homogeneous mass in G. pectinopterus, but are arranged in complete or incomplete lobules in P. sulcatus. Based on their reaction to the aldehyde fuchsin or PAS, two types of corpuscular cells are demonstrable, and the earlier suggestion that CS have a single cell type in these two species is therefore withdrawn. The stainable cells react positively and intensely in contrast to the nonstainable ones which remain more or less colourless. Although a mixture of the two cell types comprise the CS, the stainable cells preponderate.
