OTOSTOMUS. 213 
an elevation of from 4000 to 5000 feet above the sea, occupying the next region below 
that of O. ghiesbreghti, but its area is somewhat less extended. 
O. jonasi is very near O. ghiesbreghti, differing chiefly in the less rude and more 
regular sculpture, and generally also in its more slender form ; the coloration is very 
similar, but the more numerous and straighter brownish furrows between the whitish 
plaits give it a somewhat different appearance. I have never seen a specimen so 
entirely yellow as that figured by Philippi. 
Its presence in North Guatemala has not been corroborated by later travellers.

At first sight this species much resembles 0. jonasi; in O. aurifluus, however, the 
yellow stripes are on the same level as the whitish ground, whereas in 0. jonasi the 
pale brown stripes are placed in depressions between the elevated whitish plaits. ‘The 
edge of the aperture is also distinctly expanded in O. aurifiuus, but only in full-grown 
specimens. 
The locality “Vera Cruz,” quoted by Dr. Pfeiffer®, is probably intended for the 
State of that name, not the town.
