PART II. 



THE APODOUS HOLOTHUEIANS OF THE UNITED STATES 



NATIONAL MUSEUM. 



The collection contains about 2,200 specimens, representing 43 species, of 

 which 2.3 are SynaptidiB and 20 are Molpadiidfe. There seem to be eight species 

 which have never been described, two of these representing new genera. The 

 collection is almost wholly from the American coast, and chiefly from the 

 Pacific coast of North America. Most of the specimens are in good condition, 

 but many of the Chiridotas, especially those from deep water, are almost worth- 

 less. The large series of specimens of Chiridota IcEvis and discolor, and of 

 Molpadia musculus and intermedia have been of the greatest value in attemptmg 

 to solve the problems connected with those perplexing genera. The following 

 are the species represented in the collection: 



SYNAPTICS. 

 Synapta maculata (Chamisso and Eysenhardt). 

 There is a single specimen in excellent condition, collected at Cebu, Philip- 

 pines, by the "Challenger." 



Euapta lappa (Miiller). 

 There are two large specimens from Great Sound, Bermudas, which are of 

 interest as the only specimens yet recorded from those islands. 



Synaptula hydeifokmis (Lesueur). 

 There is a single small specimen of this species from Watling's Island, 



W. I. 



Leptosynapta dolabkifera (Stimpson). 



There are six good specimens of this interesting species, from Port Jack- 

 son, New South Wales, the locality where Stimpson's tyiie was taken. There 

 have been no records of, or notes on, this species published since Stimpson's 

 original description; consequently these specimens are of the greatest value m 

 determining the relationships of the species. 



Leptosyistapta iNHaiBENS (O. F. Miiller). 



There are some 130 specimens from Woods Hole, Mass., and vicinity, 10 

 from New Haven, Conn., 155 from Newport, R. I., and 8 from Provincetown, 

 Mass There are four specimens from Point Loma, California, which show no 

 characters by which they can be distinguished from specimens from the
