 white, thickly spotted with greenish gray, with a deep orange-colored 

 spot between the oral tentacles, a second long and narrow one, wider 

 in the middle, extending from the dorsal tentacles t" tin- firsl clusters 

 of papillae, and a third between the firsi and second clusters, having 

 the form of an isosceles triangle with hollowed sides, whose base line, 

 of a deeper orange, was on the median line of tie- back, and the apex 

 was situated on the side, half-way between the upper and lower sur- 

 faces. Under the tentacles, on the lefl Bide, another orange line ex- 

 isted. The anterior half of the lower surface was white, the posterior 

 half light salmon-color, showing through tie foot. Koot long,narrow,
