He said that although on two occasions (1876 and 1880) he had searched care- 

 fully through the large comatulid collection in the Paris Museum he had been unable 

 to identify the original type of Miiller's parvicirra. The number of arms mentioned 

 by Miiller, 27, is larger than in some individuals from the voyage of P^ron and 

 Lesueur which certainly belong to this species, though he did not think that they 

 can be the types of it as he formerly suggested. But he could find no reference to 

 them in any of Miiller's writings, though he must certainly have seen them when in 

 Paris, while they must also have been known to Lamarck, who based other species 

 on comatulids obtained bj' Peron and Lesueur. 



' He remarked that although Miiller's type specimen seems to have disappeared, 

 the one from Vavao which he described in 1849 is in excellent condition. 



Miiller's Alecto wahlhergii he said he was for a long time inclined to regard as 

 specifically distinct from parncirra, but finally he had been obliged to abandon this 

 view and had been forced to consider it as another variety of parvicirra. 



He noted that he had examined the types of Grube's Comatula mertensi and 

 found them to be identical with j)anncirra. His reasons for reducing armata and 

 polymorpha to synonyms of parvicirra are given. His Actinometra meyeri and Bell's 

 Actinomefra annulata were placed in the synonymy of parvicirra, and the reasons 

 for this disposition were given. 



He mentioned having found some specimens which had been distributed by 

 the Godeffroy Museum bearing the name Actinometra mutahilis Liitken, MS., from 

 Moreton Bay and the Nicobar Islands. 



Carpenter described a new species, Actinometra quadrata, in the Parvicirra 

 group which he distinguished from parmcirra by its relatively much longer brachials. 

 The type was a Challenger specimen from the Tongatabu reefs, but he said that some 

 specimens from the Nicobar Islands in the museums at Copenhagen and at Vienna 

 should perhaps be referred to it on account of the length of their brachials. Further 

 on (under parvicirra) he remarked that 1 or 2 specimens among those collected by 

 the Challenger at Zamboanga appear to approach quadrata, and it may be that the 

 latter name will have to be abandoned. 



Within the genus Actinometra Carpenter established another species group 

 which he called the Valida group, which was characterized by having the IIBr 

 series 2 and the first syzygy between brachials 3 + 4. He said that 2 somewhat 

 different tj'pes of structure are included in this group — (1) forms with IIIBr series 

 like the IIBr series, and (2) forms with the IIIBr series 4 (3 + 4). In addition to these 

 there are also species, like elongata and simplex, which normally have no IIIBr series 

 at all. 



The species which he assigned to this group, the localities whence they came, 

 and the number of specimens he examined are as follows: Actinometra elongata
