are numerous somewhat similar rods as supporting rods of the ten- 

 tacles. The pedicels however seem to have no other supporting rods, 

 than the long buttons. The C-shaped bodies , such as are found in 

 many species of Stichopus seem to be wanting. 



The rest of the collection, the 37 Dendrochirotae, represent 

 1 species of Psolus, 1 of Thyone^ 6 of Cucumaria and a new species re- 

 presentative of a new genus. There is a single, small red specimen of 

 Psoitis^ wich was taken in deep water at Cypress Point. It measures 

 12 mm long by 6 broad. The sole contains no reticulated cups like 

 those of Ps. Fabricii, but only numerous knobbed buttons like those of 

 Ps. squamatits. The specimen is too small to make its identification 

 certain. It may be Ps. japonicus Ostergren , but I am not sure that I 

 understand the difference between that species and Ps. squamatus. 

 The latter has not hitherto been recorded from any point nearer Cali- 

 fornia than the Murman Coast but it seems wiser to refer this specimen 

 to that species than to base a new species upon it. 



Of the 30 specimens of Cucumaria^ 14 represent a very small 

 (15 — 20 mm long) black species from Cypress Point, which has not 

 yet been described. It has however been the object of careful and long 

 continued study by Mr. H. P. Co wies, tho his results have not yet 

 been published. On account of its peculiar habit of brooding its eggs 

 and young, he has given it the name curata. It is not known from 

 any other locality than Cypress Point. There are 5 specimens of Cu- 

 cumaria ChronhjelmiT\).ée\, previously known from further north. There 

 is a single small specimen of the Puget Sound species C. lubrica, re- 

 ferred to above. The specimens from Pacific Grove, of both these 

 species are pure white, while those from Puget Sound were gray. In life, 

 they are said to be white. Another species represented by a single 

 small specimen (15 mm) is Stimpson's C. calcigera, hitherto known 

 from the Avestern Atlantic, the Arctic Ocean, and Behring's Sea. Its 

 occurrence at Pacific Grove, like that of Sijnapta inhaeretis and Psoitis 

 squamatus would seem to indicate a southern extension of the range 

 of a circumpolar species. 



The remaining Cucumarius represent at least 2 species, but 3 of 

 the specimens are too small to be satisfactorily determined. They are 

 obviously very young. One of the others is apparently an individual 

 of the species which S e lenk a described as ^^ Cucumaria a/é2C?a Brandt'. 

 It is 75 mm long and is perfectly white, tho in life it is said to have 

 been "yellowish with brown spots". The calcareous deposits are not 

 abundant and agree exactly with Selenka's figure. The specimen 

 moreover agrees with his descriptions except that there is only 1 Polian 

 vessel and 1 stone-canal. All of the remaining specimens are small,
