470 A. E. Ve.rrill — Marine PlanaruDis of New E)igland. 



Close to the female genital orifice there is a minute pore, from 

 which runs forward a long narrow duct (often distinctly stained 

 with carmine in the preparations). This appears to be the main 

 nephridial duct ; it was traced as far as the gastric region. 



Color pale or deep yellowish brown, greenish brown, salmon, 

 smoky brown, greenish yellow, etc., irregularly radially veined or 

 reticulated with a jDale, translucent, yelloAvish, whitish, or salmon 

 ground-color and usually with a light brown, yellow, or whitish, 

 irregular, laterally lobed median stripe, most distinct posteriorly ; a 

 small posterior pale spot ; margins pale. In some examples the yel- 

 lowish brown color appears in the form of thickly arranged, irregu- 

 lar, angular spots and patches on a pale translucent ground, while 

 the stomach, pharynx, and reproductive organs {vas deferens) cause 

 an elongated, irregular, lobulated, whitish median patch, more dis- 

 tinct on the under side ; beneath white, pale gray, or pale flesh-color, 

 or salmon, with a median, elongated, lobulated, light patch, due to 

 the stomach and vasa deferentia. 



Length of adults 20 to 25"""^ in extension; breadth, about 6 to 10"'°^. 



New Haven, Conn., to Casco Bay, Maine, common in shallow 

 water and between tides, under stones, and in tide-pools. 



Fort Hale, South End, and Savin Rock, near New Haven ; Thim- 

 ble Islands, abundant ; Newport, R. I., on piles of bridges and 

 wharves, 1880 ; Wood's Holl and Vineyard Sd,, Mass., common ; 

 Provinctown, Mass., at low- water mark, common, Aug., 18*79 ; Salem 

 and Gloucester, Mass., on piles, 187V, 1878. Quahog Bay, Maine, at 

 low-water, 1873; Banks of Newfoundland (?), T. M. Coffin. A 

 number of large specimens were taken by Mr. Gilbert Van Ingen, 

 Oct. 29, on the piles of the railroad bridge across West River, near 

 New Haven, where the water is distinctly brackish. Each one was 

 inside the shell of a recently killed barnacle [JBalanus eburneus) and 

 was evidently feeding upon its flesh. The barnacles may, however? 

 have been killed by some other agency. 



A specimen taken at Savin Rock, near New Haven, laid its eggs 

 on July 12th in large clusters placed close together on the inside of 

 a glass bottle. The eggs themselves were very small and white. 



This is decidedly the most common species of the larger planarians 

 found on the shores of New England, especially south of Massachu- 

 setts Bay. I have not obtained it during many seasons of collecting 



reproductive system. In our species its connection witli the orifice that I take to be 

 the female genital pore is very obvious in some prepared specimens, in which the 

 duct has taken a deeper stain than the surrounding parts.
