At this Station an anterior fragment of a Bhaiüania-'s,'^&z\\\\^n was col- 

 lected, the paleae of which, though in general appearance agreeing with 

 those of Bhatü. cryptocep/ia/a, still by their structure are clearly distinguished 

 from them. For on their upper side, that shows the three longitudinal.ridges, 

 the internal of which bears scale-like denticulations, the median haU' of the 

 surface is beset with transverse, irregularly bent, raised lines, 

 that on the tip of the palea acquire a net-like arrangement; the inferior 

 side of the paleae is smooth. Their number amounts to 25 at one side of 

 the dorsum, whereas in the specimens of Bhaw. cryptocephala I counted 

 only 20. The greatest breadth of the body is 2^0 nim. My colleague Dr. 

 DE Graaf had the kindness to make for me some transverse sections of 

 the head; in these sections the two pairs of eyes, situated behind each other, 

 clearly could be recognized. The eyes consist of a conical refractive organ, 

 surrounded by a cup of black pigment, like as in Chrysopetalum dcbile (Gr.), 

 according to the figure of Racovitza (loc. cit. PI. IV).
