undisturbed tentacles were extended and seemed to assist in 

 locomotion. Color, reddish-brown with longitudinal markings 

 some darker and some lighter than ground color of body. I 

 considered this specimen a ' find.' It was the only one we came 

 across." This single individual proves to be a small specimen 

 of Synapta vivipara (Oerst.) which has been recorded from the 

 Bermudas before. It agrees in all particulars with specimens, 

 from Jamaica, except that there are only eleven tentacles. In 

 the body cavity were three very young embryos, in which the 

 hydrocoel was just formed. The situation in which the speci- 

 men was found is quite remarkable, since, in Jamaica, vivipara 

 always occurs in bunches of a pecuhar seaweed sometimes 

 growing on sandy or muddy bottom but especially on the roots, 

 of mangroves. 



The other thirteen synaptids represent four distinct species. 

 There are two specimens of Chiridota rotifer a (Pourt.) pre- 

 viously known from Florida, Jamaica and Brazil, but not 

 hitherto recorded from Bermuda. The specimens are both 

 large and similar to specimens from Jamaica, but are slightly 

 different in color having a decidedly yellow tinge. There is a 

 single very small specimen (i6 mm. long) oiS. inJi(Brcns, easily re- 

 cognized by the characteristics of the calcareous ring and miliary 

 granules, as well as its pure white color. This species though 

 widely distributed throughout the north Atlantic has not been 

 recorded previously from Bermuda. Synapta roseola (Vfer.) is. 

 represented by five specimens, distinguished by their reddish or 

 yellowish color but really identified by the calcareous ring and 

 miliary granules peculiar to that species. They agree in all 

 particulars with specimens from the New England coast, hitherto 

 the only locality from which the species has been recorded. 



The remaining five specimens consist of two whole synaptas 

 and fragments of three others, entirely different from any species 

 -liitherto described. In size this new species agrees with .S". 

 inhcsrens, the largest specimen being about 175 mm. long. 

 The color is somewhat rosy, the prominent verrucee being well 

 supplied with the reddish pigment so abundant in 6'. roseola. 

 The verrucae are quite numerous, over 500 to the square cent!-
