July 7, 1932, from Boyden collection. Concho dyte s domestica . Pontonid 
from Pinna. (Boyden had opened about 3 6 pinnas and found only this one) 
Clear colorless, of glass-like transparency, with reticulating opaque 
lines of white. Outer blade of tail fan with small, nearly circular clear 
area, inner blade nearly wholly clear, large clear central area. Telson clear 
except around lateral spines and little hinder distal piece. Fringing hairs 
everywhere wholly transparent. 
Ambulatory legs are transparent except at distal and proximal extremities 
of joints, more of the opaque at the distal rather than the proximal end. 
Dactyli transparent throughout and propodi except for very little of the 
opa«jue at extreme proximal end. 
Antennal and thin flagellum of antennules alternately transparent and 
opaque, otherwise antennules and peduncles have very little opacity and 
what there is is thin and wishy-washy, forming no definite pattern. Antennal 
scales fainly opaque around margins, otherwise wholly transparent.
