outer ovate to lanceolate, the body short, but tipped with 

 a very stout and long, yellow, roundish spine, i' long, or 

 equaling the head, the inner scales with shorter spines 

 and the innermost series of delicate, linear, subulate, thin, 

 red-tipped scales, shorter than the outer spines; corollas

 sand, along the bottoms of the Pahria river, at Pahria,
