arian. Moseley says, that in Sarcophytum the ova are 7 mm. 

 in diameter, but having examined a few sections of the actual 

 specimens described by him, I think this must be a misprint 

 for 0.7 mm. In Alcyonium digitatum the ripe ova are only 

 0.5 mm. in diameter, and in nearly all Alcyonarians the ova 

 are approximately the same size. 



The smaller specimen is a male, the sperm sacs not being 

 quite mature.

Four of several specimens obtained when trawling in 

 irt. 32° 53' S., long. 28° 12' E. (about 17 miles E. of East 

 London), depth: 45 fathoms, bottom; sand and mud and 

 « orallines. were sent to me. 



They are all top-shaped, the crown being rounded in out- 

 line and presenting no well-marked edge as in Sarcophytum. 

 The stalk is, in the preserved specimens, variously wrinkled 

 and varies considerably in the degree of attenuation it pre- 

 sents. The specimens are white, but there is a ring of bright 

 red spicules round the base of the exsert portions of the 

 polyps, and the spicules of the tentacles and the body wall 

 of the exsert portions of the polyps are bright yellow. 



Numerous siphonozooids are crowded between the auto- 

 zooids, the mouth of each one opening in a small convex 

 protuberance. Owing to this protuberance and their 

 relatively large size the siphonozooids are much more con- 

 spicuous than those of other species of the genus. 



The specimen (IV.) I dissected was 10 mm. in length, 

 6.5 mm. in diameter at the widest part of the crown, and 3.5 

 mm. at the narrowest part of the stalk. The corresponding 

 measurements of the other three were : (I.) 38, 15, 5 : fIT.) 

 TO, 6. 4 ; and (III.) 21,4. 1.5. No. TI. is characterised by 

 having a short broad stalk, No. III. by having a very long and 

 slender stalk. 



The yellow spicules which occur in abundance in the ten- 

 tacles are rods with rather swollen extremities covered with 

 warts (Plate VI., C") .05 mm. in length, by .015 mm. in 

 breadth. The body walls of the autozooids are strengthened
