and in a few they are altogether wanting. The thorax is sometimes 

 marked with depressions, varying in number from one to four ; and in 

 what may be termed the apterous sex the eyes are either black or 

 orange, or of any intermediate shade. 



It is nevertheless well distinguished from its congeners by its large 

 size and long pubescence, also by the greater dilatation of the ante- 

 rior part of the thorax, by the oblong shape of the elytra, and from 

 all, except P. Maria, by the obtuse abdomen.

Notes on Sea Anemones. — For the information of the anemone-loving readers of 

 the 'Zoologist' who may visit Tenby, I send the results of my researches at that 

 charming spot during three weeks' residence in July last. The spring tides were not 

 very favourable for collecting, owing to a strong west wind, which blew back the spray 

 and prevented me from visiting Lidstep Caverns and the Woolhouse Rocks, the latter 

 designated by Mr. Gosse as " that rich preserve of zoophytic game." I availed myself 

 of the assistance of the local collectors, Jenkins and his son Lewis, most honest, atten- 

 tive and civil men, whom I have great pleasure in recommending to the notice of all 

 aquarian naturalists visiting Tenby. The following are the species of Actiniae which 

 I secured, in addition to specimens of Echinus miliaris, Holothuria, Aplysia, Doris, 

 Eolis, Terebella, and many beautiful kinds of star-fishes: — 



Sagartia nivea. Very fine specimens and plentiful at Castle Rock, and var. 

 obscurata on the Ridge between Caldy and St. Margaret's Islands. 



S. rosea. Fine specimens, but not very numerous, at St. Catherine's and the 

 Ridge. 



S. venusta. Beautiful specimens at St. Catherine's, and a less brilliant variety at 

 the Ridge. 



S. viduata. Very scarce. Three specimens only were met with, and those at 

 Castle Rock. 



S. Bellis. Rather scarce. Var. tregiensis found at the Ridge, and several of the 

 var. modesta in the same locality. 



S. Troglodytes. Very numerous. Small specimens on Gascar Rock, and fine ones 

 at St. Catherine's. Vars. scolopacina, Aurora and auricoraa taken (one specimen only 

 of the last-mentioned). 



S. miniata. Good at Castle Rock, but small. Fine specimens dredged off St. 

 Gowan's Head. 



Bunodes gemmacea. Beautiful specimens and tolerably plentiful on the south 

 and west sides of Caldy Island. 



B. crassicornis. Fine specimens dredged off St. Gowan's Head. 



Anthea Cereus, vars. smaragdina and rustica. At the Ridge. 



Actinoloba Dianthus, vars. brunnea and sindonea. At St. Catherine's and Castle 

 Rocks. 



Actinia Mesembryanthemum. Abundant everywhere, and, although of the com- 

 monest kind, not to be despised, for many are very pretty. 



Several of the A. Dianthus were double, i.e., two disks sprouting out of one column.
