FROM THE CARBONIFEROUS FORMATION. 171 



Euphoberia Carri, nov- sp. 

 PI. 12, figs. 4, 9-12, 14-19; pi. 13, figs. 16, 18. 



Five specimens, all showing relief and intaglio, are preserved. The first (PI. 12, fig. 1G), 

 is bent into the shape of an |_ and presents on the longer anterior limb a dorsal view, 

 but the hinder portion is somewhat twisted as well as bent so as to be partly lateral ; both 

 extremities are broken off. The body thus preserved is largest anteriorly, nearly equal 

 on the front half of the fragment ; behind this it tapers at first considerably, afterward 

 less rapidly, so that the posterior extremity is scarcely more than half as broad as the 

 anterior portion ; the body is very strongly flattened, but may have been rounded. 

 The fragment is about 58 mm. long;, 6.5 mm. broad in front and 3.5 mm. broad behind. 

 There are twenty-four or twenty-five segments, about twice as broad as long ; there is 

 little sign of any ridging in the anterior part of the body, but toward the posterior 

 part the spiniferous portion is clearly seen to be elevated above the plane of the 

 remainder of the segment. The whole body is minutely and closely granulated like a 

 very fine shagreen (PI. 12, fig. 4, showing the first segment enlarged) ; there are also some 

 slight signs of the same circular disks that have been described in other specimens, and 

 which are of the same size as in Acantherjjestes major. 



The subdorsal spines are placed in contiguous rows, which are sejiarated by a considera- 

 ble space from the lateral row, where only are any preserved entire, and that only 

 in a few places. They are of more uniform length than the width of the body (PI. 12, figs. 

 17, 19), being about half as long as the width of the body where the latter is slender, and 

 less than one-third as long in the anterior broader part ; they are almost simple, being 

 conical and sharply pointed beyond a more or less mammiform base, curving slightly back- 

 ward, especially beyond a minute anterior thorn or spinule which springs from the end 

 of the basal third, and is only slightly divergent from the main spine. The legs are pre- 

 served at only one part of the fossil, in the slenderer portion of the body ; they appear 

 (PI. 12, fig. 18) to taper throughout and almost uniformly, or a little more rapidly on the 

 apical than the basal half; there is plainly a median carina, and on some it even extends 

 throughout the length of the leg, but it is impossible to tell where the joints are ; the 

 whole leg is 4.75 mm. long, where the width of the body is slightly less than that. 



The second specimen (PL 12, figs 9, 12) probably presents the animal throughout its 

 entire length, exhibiting a side view of the creature, doubled upon itself downwards in 

 front of the middle, the front portion considerably curved and overlapping the other. The 

 body tapers forward, but not very strongly, from about the seventh segment ; the broadest 

 part appears to have continued for about ten or twelve segments (the bend renders this 

 uncertain) and then to have tapered rapidly, for the hinder third is uniform and nearly half 

 as broad only as the broadest part ; the body was plainly cylindrical, about 42 mm. long, 

 4.25 mm. broad at the broadest part and 2.5 mm. in the apical half. 



The head (PL 12, figs. 14, 15) consists of a single segment considerably appressed, well 

 rounded, not so long as the next segment behind it, but much deeper than it and droop- 

 ing ; what little can be seen of the surface is pitted and rugose ; something which look 

 as if it might be an antenna droops from the upper anterior margin of the head, curved,s 

 tapering, and apparently rugose like the head, or else broken up into a great number of
