To quickly assess the difficulty of the text, read a short excerpt:
The egg strings when first extruded are conical, largest at the base and tapering to a single egg at the tip; when fully developed they are cylindrical and considerably shorter than the body; eggs in 5 or 6 rows, about 10 eggs in a row. Color (preserved material), a uniform light brown without pigment markings. Total length, i mm.; cephalothorax, 0.60 mm. long, 0.40 mm. wide. Length of egg strings, 0.60 to 0.80 mm. {lanceolatus , lanceolate, alluding to the general body shape.) Remarks. — This ...species is not associated as yet with any glochidium, but may well take the place of cceruleus or centrarchidaruni or versicolor. Its presence on the shad indicates that this fish would make a good host for some of the gill glochidia as well as for those already foimd upon its fins. Like other parasites found upon the herrings and their close relatives, this species does not infest any fish except its immediate host, and hence it is not likely to be found except on the gizzard shad. Ergasilus nigritus, new species.
