We have, on a former occasion,“ alluded to the close connection of this 
group with the Coronelline, through Cemophora and allied forms; our 
author perceives exactly the same affinity, but renames the genus just 
mentioned, Stasiotes, Ficimia and, as Giinther remarks, Brachyurophis, 
are probably related to Rhinostoma; the latter is no doubt connected to 
the beautiful Heterodon semicinctus, by Dr. Peters’ Simophis. Hetero- 
don d’ Orbignyi connects the red-ringed species with our northern type; 
thus we are led from Sonora semiannulata to Heterodon platyrhinus! 
Ours is indeed no “ Ariadne’s thread” if we are led to such results. But 
we have perhaps only lost the clue. ; 
We have only to remark, regarding Prof. Jan’s species of this group, 
that Chilorhina Villarsii is Sympholis lippiens, and that Stenorhina 
quinguelineata is not a variety of, but a very distinct species from, the 
ventralis—or Degenhardtii, as Jan agrees with Peters in calling it. 
Thus it appears that Prof. Jan’s work, like that of most others, is not 
free from oversights, many of which are not so excusable as some, whi 
may have been occasioned by nearly simultaneous publications. 
14, Note on the “Glass Coral” of Japan, (in a letter to Prof. Siutmay, 
Jr., from Wittram Srimpson, dated Smithsonian Institution, Feb. 6, 
1863. 
“The ‘glass-coral’ to which you refer is the Hyalonema mirabilis of 
Gray, which is found in the seas of Japan, and is one of the most beau-
