To this species I have applied the name greenmani, in honor of 

 my friend Milton J. Greenman, M. D., Assistant Director of the 

 Wistar Institute of Anatomy and Biology, whose hospitality I enjoyed 

 during my collecting trip at Sea Isle. 



Ämphiporus greenmani was abundant in Ludlam Bay, Sea Isle, 

 living with Zygonemertes and Tetrastemma in the sea-weeds with 

 which this inlet of the ocean abounds. 



4. Ämphiporus glutinosus (Verr.). 



The brief description given by Verrill of this species, may be 

 supplemented by the following anatomical notes: 



The lateral nerve chords commissure at the posterior end of the 

 body, above the intestine. 



The Oesophagus empties into the rhynchodaeum. 



No sensory hairs are present in the body epithelium. Large, 

 rounded gland cells, which stain with haematoxylin, are very abundant 

 in the epithelium, producing the viscid slime which this species pro- 

 duces in such abundance, and which is very characteristic of it. 



Rhynchocoel extends posteriorly as far as the commissure of the 

 blood vessels. There are 11 longitudinal nerves in the proboscis. 

 The central stilet is larger than its basis; the latter is rounded and 

 most swollen posteriorly, constricted medially ; Fig. 18 shows the usual 

 form, while in Fig 19 is to be seen an abnormal stilet basis. There 

 are always two lateral stilet pockets. 



The paired intestinal coeca extend to the dorsal brain com- 

 missure. 



Nephridia not more than one-third the length of the oesophageal 

 region. 



The cerebral sense organs reach the brain. 



The cerebral gland is voluminous, but does not extend behind 

 the brain. 



One or two ova are found in each ovary. The ovaries are 

 numerous, as many as 4 or 6 being found on each side, on a given 

 frontal section ; while in the malesj as many as 12 testicles may occur 

 on each side. Both ovaries and testicles are placed above and below 

 the nerve chords.
