Conchotrema canna (Price, 1916)

Diagnosis: Fine tubules, freely branching and anastomosing, so as to form in dense development an irregular mat of several strands' thickness; borings vary slightly in diameter, rarely more than 0.2 mm; seldom unbranched for as much as 2 mm between nodes; branches straight, more or less curved, to highly sinuous. Apertures numerous.
