Fam. Agalmidae Brandt 35. 

 Agalma Brandt. 



43. Larva of Agalma spec. PI. XIII, fig. 97. 



Stat. iiS. Lat. i°38 N., Long. i24°28'.3E. Cat. 157 A. formald. 47o- One specimen. 



This single specimen of an Agalma is e.xceedingly small, the diameter of the very rounded 

 little specimen being about one mm. and it is very remarkable that magnified about 25 times 

 (PI. XIII, fig. 97) we find that not only the pneumatophore is well-developed but at the same 

 time we find three buds of nectophores in different stages of development, two siphons, one 

 tentacle with tentilla and three well-developed pal pons; all the appendages are situated closely 

 packed together. It was the shape of the uniform tentilla, well-known in the larval stages ot 

 Agalma, which made us identify this specimen with that genus. They are of considerable size 

 in comparison with the whole specimen. 



Our specimen bears a great resemblance to Leuckart's larva of Agalma Sarsii (53 p. 39). 

 But he found only one siphon and the diameter of the larva was i'/^ mm. 



So the specimen of Agabna-\2LX\2. of the Siboga expedition is the smallest and most 

 compact one that has ever been found. 



Mature Agalma were entirely absent from our material. 



44. ? Young Agalmopsis M. Sars. 



.Stat. 203. Lat. 3°32'.5S., Long. 124° 15'. 5 E. Cat. 136 A. ale. 90°/^. One specimen. 



No e.xample of an Agalmopsis identical with any of the species of S.\rs, as defined by 

 later authors, was found by the Siboga. An absolutely incomplete specimen, entirely altered by 

 preservation, of a total length of 4 mm. might perhaps be reckoned to this genus. The shape 

 of the unique bract, namely, an elongate, foliaceous one, with three small groups of cnidocysts 

 at the three terminal points, shows a certain resemblance to the bracts of Agalmopsis. 



The specimen consists of a badly preserved pneumatophore, three hardly recognizable mature 

 nectophores and a siphosome with no other appendages than the above-mentioned young bract.
