84 THE NAUTILUS. 



brown, the usual pale markings white (no yellow) ; sole pale grey 

 with a slight yellowish tint. All were alike. In the colorless 

 slime this agrees with var. grisea Roebuck, but the color and 

 markings of the skin are those of var. umbrosa Philippi. Is the 

 loss of the yellow color due to the peculiar environment? 



Limax maximus L. At Berkeley^I obtained a very fine spotted 

 form; mantle with many black spots; body pale grey, slightly 

 reddish laterally, with four rows of black spots, and at sides ir- 

 regular small black spots. The dorsal spots are elongated, and 

 the animal is referable to the variety cellaria.

Tethys (Neaplysia) californica (Cooper). — Last August, when 

 my wife and I were at La Jolla, California, we obtained six 

 living specimens of this species. The largest was ten inches 

 long, and four high, counting the parapodial lobes. The 

 animals exuded a deep purple substance, which soon turned 

 brown. The following description of the color is from life : body 

 rather coffee brown, marbled with dull crimson and thickly 

 sprinkled with large, mostly circular, dark brown or almost black 

 spots, irregularly placed and of different sizes; there is also a 

 fine dark reticulation. Inner side of parapodial lobes heavily 

 barred with brown-black and whitish, the dark color much 

 more extensive than the pale. Sole dark purplish brown, much 

 wrinkled. There is variation in the size of the dark spots and 

 the distinctness of the crimson markings, which may be very 

 obscure. This appears to be quite distinct from T. ritteri Ckll. , 

 and I was informed that the biologists of the Scripps Institution 

 were familiar with a second, less-marked, species, which doubt- 

 less is T. ritteri. — T. D. A. Cockerell. 



The Solenopsidae. The extinct family Solenopsidse has for 

 its type genus Solenopsis McCoy, the name of which, being pre- 

 occupied, was altered to Solenomorpha in 1903 (Nature, April 16, 

 p. 559). The family name has however continued in use, so it 

 may be well to point out that it must be altered to Solenomor- 

 phida. — T. D. A. Cockerell.
