A very small species, attaining a maximum length of about 0*06. 

 Body elongated, the greatest depth being contained probably more 

 than five times in the total length ; head and branchial apparatus 

 occupying one fifth of the total length. Spines all short and broad, 

 the longitudinal ridges being sometimes tuberculated. Pectoral fin- 

 spines stout and slightly arched, about equal in size to the first 

 dorsal ; four pairs of very short and broad, small, intermediate 

 ventral spines ; pelvic fin-spines about half as large as the pectoral. 

 First dorsal spine shorter, broader, and more curved than the second, 

 situated midway between the pectoral and pelvic pairs ; second 

 dorsal spine comparatively straight, slender, and pointed, slightly 

 more remote and much larger than the anal. Scales mostly small,
