not one being found for a long time. Though they have not 

 occurred in any number in the Bay, yet on ahnost every excursion 

 at this time one or two came up in the dredge, usually from the 

 hard bottom off Craigmore and Huntly Place, and the nullipore bed 

 at Ardbeg, but sometimes even from the mud their feathery rays 

 would be seen trying to get free from such an uncongenial position, 

 in which Ophiocoma jiliformis (Miiller) is so much more at home, 

 always appearing clean even in such a dirty habitat, while the 

 Comatidas seem to have been overtaken when creeping over the 

 surface, and rolled into the netting over and over, till completely 

 enveloped. Like other Star-fishes in the Bay, the Comatulas 

 appear to attain to a good size, the length of a single ray, in a 

 fine specimen, being 7J to 8 inches. 



This species is now named Anted on Milleri, and has been 

 separated from A. rosaceus. In the former the centrodorsal 

 plate is entirely covered with dorsal cirrhi, while in the latter only 

 the sides are so covered and the central portion is naked. It is a 

 smaller species, Norman stating the size to be 4 J inches from tip 

 to tip of the arms or rays, while A. Milleri is 11 inches from tip 

 to tip — our largest, however, will be 16 inches. Solaster papposa 

 (Linn.) is not unfrequently met with also of large size, while S. 

 endeca (Linn.) is more rare. Goniaster Templetoni (Thompson) 

 was obtained at this time. Amphidotus roseus (Forbes) is not 

 uncommon; and Echinocyamus pusillus (Miiller) is occasionally 

 detected. 



Of the Holothuriadse Cucumaria pentactes (Miiller) may be con- 

 sidered as occurring everywhere. C. fusiformis (Forbes and 

 Goodsir) was added to the list in 1869 ; and C. Hijndmanni 

 (Thompson), in 1868. When first obtained the latter was 

 covered with small stones, from which its head projected at an 

 angle, and continued in this stiff position till night, when it 

 became more lively, and, throwing off the stones, proceeded on a 

 survey of its new quarters. 



At the same dredging Thy one jmpillosa (Miiller) was found. 

 Most of these Holothuriae seem to be nocturnal animals, and to 

 get lively after dark, displaying their tentacles in all their beauty; 

 on the second night, however, poor Thyone put an end to itself, 

 somewhat after the Japanese fashion of the happy despatch, 

 evacuating its interior, the whole of the dental apparatus and 

 intestine. The long narrow form of this dental apparatus shows
