PKOE. A. C. HADDON ON TWO SPECIES OE 



of scapus white. Tentacles with a row of small madder-brown 

 spots on their oral aspect. Disk with madder pigment. 



Dimensions. Specimen a : Diameter of base 20 millira., dia- 

 meter of lower portion of scapus 15 millim., height 7 millim. 

 Specimen h : Diameter of central portion of scapus 9 millim., 

 height 8 millim. 



Habitat. Sullivan Island, Mergui Archipelago; 6 fathoms. 

 January 13, 1882. 



This species is so closely allied, to the "Phellia pectinata " of 

 E. Hertwig, as described in his ' Challenger ' Report, that there 

 can be no doubt that they must be placed within the same 

 genus. 



The genus PJiellia as defined by Grosse (Ann. Mag. Nat. Hist. 

 (3) ii. 1858, p. 192, and 'Actinologia Britannica,' p. 134) and 

 accepted by Verrill (Trans. Connect. Acad. i. 1868, p. 489) and 

 Andres (Le Attinie, 1884, p. 117) is well characterized; the 

 scapus may be rugose or wrinkled, but distinct nodules are 

 absent. 



"While apparently agreeing in many respects with this genus, 

 in Hertwig's form the scapus terminates " above in twelve 

 knobs, which are prolonged on to the inverted soft-membraned 

 section [capitulum] as twelve longitudinal combs." The new 

 species just described also possesses twelve nodules. I am 

 indebted to my friend Canon A. M. Norman for an Actinian 

 which closely resembles the form depicted on Plate XX. fig. 1, 

 which he dredged twenty years ago at Shetland, and which I am 

 elsewhere describing (Trans. Hoy. Irish Acad.). Lastly, Gosse 

 described in 1859 a new British Sea- Anemone which he named 

 Horonathia Margarita) (Ann. Mag. Nat. Hist. (3) iii. 1859, 

 p. 47, also Actin. Brit. p. 219, pi. viii. fig. 1), the new genus 

 being thus diagnosed: — "Base adherent, greatly expanded. 

 Column pillar-like, much corrugated, surrounded by a single 

 horizontal row of warts. Disk slightly concave, scarcely ex- 

 ceeding the column. Tentacles moderately long and slender, 

 perfectly retractile. There is but a single known species, H. 

 Margarita." This species has only once been recognized since ; 

 P. E. Schulze records it from 9G fathoms off N.E. Scotland (log. 

 no. 79) on Fusus awtiqvius (.Jahresb. d. Com. z. wiss. Untcrsuch. 

 d. deutschen Meere (JSxped. 1872), 1875, p. 140). 



Anatomical delailn are wanting for the type species of both of 

 Qto ' genera Phellia and llonnallria ' ; but it appears pretty
