Crossword-Solution: LACUNAR 7 letters, 3 clues 🏆 scrabble score: 9

Non ebur neque aureum Mea renidet in domo lacunar, Non trabes Hymettiae Premunt columnas ultima recisas Africa, neque Attali 5 Ignotus heres regiam occupavi, Nec Laconicas mihi Trahunt honestae purpuras clientae.

Nettleship has pointed out, this seems to indicate that there are two words, _laquear_ from _laqueus_, meaning chain or network, and _lacuar_ or _lacunar_ from _lacus_, meaning sunk work.

These consist of what is known as _erectile tissue_, a spongy mass within whose lacunar spaces a large quantity of blood can, in certain conditions, be retained.

Whilst the general visceral cavity forms a lacunar blood-system or series of narrow spaces, connected with the trunks of a well-developed vascular system, that part of the original coelom surrounding the heart and known as the Molluscan pericardium is shut off from this general blood-lymph system, and communicates, directly in _Nautilus_, in the rest through the renal sacs, with the exterior.

There are no lacunar blood spaces with ill-defined or absent walls except for a sinus surrounding the intestine, which is at least frequently present.
