A speeimeu of 26 mm. is still cxteriitilly symiuctrical and is u.xtrcincly similar to 

 the example of B. podas figured liy Kyle (t.c. p. 98, fig. IG). I count 8G dor.sal and 

 59 anal rays and :!8 (10 + :28) vertchrac

Two examples of C to 7 mm. are rather similar to .S. /(^''/(vm if thi.s size descril km] 

 and figured liy Kyle (t.c p. lo2. pi. iv. figs. 41-42), but the abdominal appendix is 

 lacking, and the distribution of the pigment is somewhat different. A specimen of 

 11 mm. has already metamorphosed, showing that the change takes place at a smaller 

 size than in the Eurojieau species.
