222 Miscellaneous. 



About the end of April, I found beneath a flat stone, in a cavity oc- 

 cupied by a large flavous species of ant, a living Cremastochilus va- 

 riolosus, but laid no stress upon the occurrence, as I supposed it to 

 be accidental. On the 16th of May I took three individuals of C. 

 Harrisii together, under similar circumstances, and kept them alive 

 for twelve days. On the 25th of May I found a second individual 

 of C. variolosus, in an ant's nest. The locality is a southern hill- 

 slope covered with Castanea, Pinus mitis, Acer, Carya, and Kalmia, 

 the soil siliceous. The genus is extremely rare ; although tolerably 

 successful in collecting, and my residence is near the locality, these 

 are the first living individuals I have seen. In confinement they 

 burrow beneath the earth in which they are placed, the head, from 

 its peculiar form, being well adapted for this purpose. 



The genus Chelifer is also found in ant-nests, where it is probably 

 attracted by the immature Thysanura which occur there ; but I re- 

 cently found nine individuals apparently parasitic, lodged near the 

 extremity of the abdomen, beneath the wings and elytra of a living 

 Alaus oculatus, the early stages of which are passed in ash-trees. —

Myochama Anomioides. 

 To the Editors of the Annals of Natural History, 



Gentlemen, — The following notice may perhaps prove of interest 

 to your conchological readers : — 



It is generally asserted that Myochama Anomioides is strictly con- 

 fined to Trigonia pectinata, but such is not the case, as I have 

 dredged it on the following genera, Pandora, Pectunculus, Struthio- 

 laria. Two specimens I dredged last January in sixty feet of water 

 in Port Jackson, on a bottom of coarse sand and shells. The first 

 specimen I procured was on a dead valve of a species of Mytilus 

 which I sent home, since which I have dredged for days in the same 

 spot and procured four, three of which were on dead valves of 

 Cleichthanus, and one was on a round piece of sandstone. 

 I remain, Gentlemen, yours truly,

On the Eyes of the Balanus. By Dr. Leidy. 



Dr. Leidy remarked, that the existence of eyes in the perfect con- 

 dition of the Cirrhopoda has been denied by all anatomists up to 

 the present time, but its presence in the larva or imperfect stages is 

 very generally acknowledged. Several years since, having received 

 some living specimens of Balanus rugosus adhering to an oyster, he 

 submitted them to dissection, in the course of which he noticed 

 upon the dark purple membrane which lines the shell and muscular 

 columns running to the opercula, on each side of the anterior mid- 

 dle line, a small, round, black body, surrounded by a colourless ring 

 or space of the membrane, which, upon submitting to a low power
