forming a narrow end beneath the six (6) coarse teeth, which suc- 

 cessively increase in size. 



Tubes unattached, yellowish, of good size, gradually tapered, 

 rounded, and somewhat contorted, the surface roughed by numerous 

 conspicuous irregular growth lines crossed on one side hy three well- 

 separated rather delicate longitudinal often lamellar-like lines. 



Three similar species have been recorded from the West Indian 

 fauna. Eupomatus sanetoe~crucis Morch, 1863 (as Eucarphus), from the 

 Island of St. Croix is described and figured as having a minute spinelet 

 on the outer (?) surface of each spine of the upper cup of the operculum 

 at about the middle, thus if correct (they usually occur on the inner 

 surface) representing a connecting link between typical Hydroides 

 with two or more spinelets and typical Eupomatus destitute of them. 

 Eupomatus spongicolus Benedict. 1886 (as Hydroides), from Gulf of 

 Mexico in sponges from 26 fathoms, has numerous (14-18) simple long 

 slender curved spines with long basal inner spinules on upper cup of 

 the operculum and about 65 narrow deep points on edge of lower one. 

 Eupomatus Floridanus nom. nov. for E. uncinatus Ehlers, 1887 (non 

 Philippi, 1844), from 7 fathoms off Cape Dear Rio, Florida, has 11 very 

 long, much curved spines with inner basal spinule on upper cup and 

 about 30 deep points on edge of lower one. This does not agree with 

 the operculum of E. uncinatus from the Mediterranean (a fact men- 

 tioned by Ehlers). From mass of 2 or 300 tubes in Yale Museum, a 

 number of dried animals were taken showing the opercula and collar 

 setae in good condition. There are 9 or 10 spines on the upper cup 

 which are stiff nearly straight, being curved only near the tip and so 

 abruptly as to appear angulated on the outer surface, the inner basal 

 spinule inconspicuous wart -like; they are very like the figure given 

 by St.-Joseph, 1906. On the American coast the Eupomatus dianthus 

 (Verrill) Bush as figured by Benedict, 1886 (as Hydroides), is a closely 

 related species. 

 Jomatostegus brachysoma Schmarda. 



One beautifully preserved animal has been received from the Island 

 of Dominica, W. I., from Mr. A. H. Verrill. Entire length 45 mm.; 

 operculum 15 mm. of which 5 mm. belongs to its homy end; thorax, 

 about 5 mm. 



The very large operculum arises abruptly without a peduncle from 

 the base of one of the branchial lobes. It is cornucopia shaped with 

 very oblique end and very conspicuous thin membranous side appen- 

 dages, gradually increasing in width from the base to the free rounded 

 end lobe. There are three semitransparent horn-colored somewhat
